Healer with preferencial troop

Hello,
First, sorry for my english :)
I searched, but dont found the same idea. It is possible? I dont know, but will be good.
Well, I had some bad experiences with healer + giants.
When we use to attack, some times the healer use your power in other troops, and giants die.
Then, i think could have preferencial troops for healer, in case, giants.
If you use without giant, she cure like now, the troops that are being attacked
This is my idea, thank you

Edit:
Sorry, posted in wrong place.
