Just wrote myself a wizard figured I'd share it.

It asks for healers in order then one spell for each of those healers and make a command to heal each of your characters.

Example Command that it creates:

Cast Healing Wave On Catoblock From Catowave
If %Heals% >= 2
Cast Healing Touch on Catoblock From Catoboom
Endif
If %Heals% >= 3
Cast Heal on Catoblock From Catoshadow
Endif

It will also always heal from your main healer even if you have 0 healers set.

Make sure to choose healers in the same order you did in the Do This First Wizard and select the spells in same order.

Wizard Code:

#Wizard Heals
#Ask Name,Type of Heal
#Select Healers, Toons, Select Healers(Main Healer First)
#Select Spell, Spells,Select Heal Spells(Same order as healers)
#Loop i,1,[Toons.Count]
#Command [Name]Heal[Toons(i)]
Cast [Spell(1)] On [Toons(i)] From [Healers(1)]
#Loop j,2,[Healers.Count]
If %Heals% >= [j]
Cast [Spell(j)] on [Toons(i)] From [Healers(j)]
Endif
#Endloop
#EndCommand
#Endloop
#EndWizard

I have also attached this wizard file just download and place it in your C:\GameCommanderPro\Game Support directory.

Note:
This does not have a default key bind so the commands will be in WizardUnbound*
