Need help to improve my healing macro

[krax]

I play a healer and iv created a macro that let me singel heal grp members by pushing one button. The thing i dont like about it is that it needs to change target to the one im healing. Another problem is that if i heal a pet class it will target the pet if i click it a second time.

Does anyone know if there is a % or other command i can put in the target of the spell ? (need to be a generic so i dont need to edit it every time i raid.)

I use profit but i dont like the click to heal in grp takes me too long.

The macro i use is this. i have 5 of those only thing that changes is the grp member number.

Command : /cancel_spellcast
Command : /target_group_member 0
Spell : heal 1
Spell : heal 2
etc
