So Im looking at Blizz's Full Reflect System, and thinking of a way to add a bit of strategy to battles.  For example, an enemy that heals itself every round would reflect spells back.  But to target the enemy with Magic, I'd need to be able to cast an offensive spell on a Party Member that also has Reflect on.  IE, cast Fire on a Party Member and it Reflects to hit the Enemy.  Unfortunately, there is nothing in the Scope dropdown menu that allows a skill to target Anyone, hence I need to turn to a script.

The other thing I was thinking this might be useful for is Vs Undead.  I think there may be a script for this already, where Friendly Spells cast on Undead have the Opposite Effect.  IE Heal Spells Damage Undead, but first, I'd need to be able to Target the Undead with a Friendly Spell.

Any suggestions?

Took me a good chunk of time. I was naturally bored so I felt to give it a go. Note that this was written with the default battle system in mind since you didn't mention any (I probably wouldn't have tried if you did :P)

Target Anyone Scope
Version 1.0

By KK20
===============================================================================
 -[ Introduction ]-
 This small script allows the player to make single target scopes reverse its
 intended target. In other words, you can now choose to Heal a monster or one
 of your allies.
 
 -[ Instructions ]-
 1.) Scroll down to the configurations and locate Constant TARGET_ANYONE_TAG.
     Change the string associated with it if you like.
 2.) Modify the key press that will allow the player to shift between targetting
     the party and the troop.
 3.) Create a new element in the Database. Name this new element the same as you
     have TARGET_ANYONE_TAG assigned to.
 4.) Apply this new element to skills or items that you wish to have this
     effect.
 
     ~ NOTE: The effect will only work if you set the scope to "One Enemy"
             or "One Ally".

 -[ Compatibility ]-
 * This script was made with the default battle system in mind. Custom battle
   scripts will most likely not work with this script without edits.
 * Not tested with SDK
 * Changes made to Game_Actor, Game_Battler, and Scene_Battle

Awesome!  Yeah I do have a custom battle script, but let me worry about trying to get that to work properly with it.  Quick request, the system Im using is a Front View, is it possible to set the Change Party Keys to Enemy on Input::UP and Party on Input::Down?

So, um, although it is pretty much what I wanted (at least for Undead), it seems that Heal spells seem to HURT bad guys...  Hopefully you have a quick fix for that?

I seriously appreciate the work you put into this, I know it isnt easy!  Thank you very much!

As for the healing, I got mine working the way it should. I just made a new element called "Heal", made any monsters that could be damaged by healing a rating of F, and....profit. Maybe your elements are just wonky? Or you changed Heal's base damage value, which should be a negative number. But anyways, no problem for the help  ;)

I havent gotten to trying to integrate it yet, so I just tried it in a new empty project to test this script out.  I'll try adding a Heal State and give it an F to see if that helps.

Works pretty good!  Any suggestions on how to make a Revive or Resurrect Spell work the same way as Instant Death?

 :???:
Well, to create an instant death skill, all you have to do is make the skill apply the state "Knockout". So...to revive, all you do is make the skill remove "Knockout". There is a revival skill (Raise) whenever you start a new project--just make the skill look like that.

Quick Fix: Item Scope

Spoiler: ShowHide
=begin
===============================================================================
Target Anyone Scope
Version 1.0

By KK20
===============================================================================
 -[ Introduction ]-
 This small script allows the player to make single target scopes reverse its
 intended target. In other words, you can now choose to Heal a monster or one
 of your allies.
 
 -[ Instructions ]-
 1.) Scroll down to the configurations and locate Constant TARGET_ANYONE_TAG.
     Change the string associated with it if you like.
 2.) Create a new element in the Database. Name this new element the same as you
     have TARGET_ANYONE_TAG assigned to.
 3.) Apply this new element to skills or items that you wish to have this
     effect.
 
     ~ NOTE: The effect will only work if you set the scope to "One Enemy"
             or "One Ally".

 -[ Compatibility ]-
 * This script was made with the default battle system in mind. Custom battle
   scripts will most likely not work with this script without edits.
 * Not tested with SDK
 * Changes made to Game_Actor, Game_Battler, and Scene_Battle
