/target party1
/cast <heal_spell>

having something like this pretty much renders 5 buttons for the same spell, which will have me run out of buttons (brain memory where the damn button is) rather fast
I use F1-F5 for all of my groups and have plenty of buttons left. Are you using Trinity Bars, Bongos or some other key layout mod?
Additionally, when my Shaman (healer) casts on anyone but the tank, it uses Chain Heal.
And if the toon they are casting on has some sort of aggro reduction or shield, I do that as well, all at the same time.

Example:

Shaman uses F2 to heal the mage.
Mage has F2 set to cast mana shield. (I also have Ice block in there with a +shift)

Sorry, I know it's not what you were looking for, but it does work.
