RPG MV SPELLS THAT CAN'T TARGET CASTER.

In my game I have the four basic classes, thief, mage, tank, and healer, my current problem is the healer, I need her to not be able to target herself with healing spells, as they require her to sacrifice her energy to do so, and this just makes it cheap. And sorry I gotta add, is there anyway to set up a custom command like guard and attack?

I checked and he has nothing with this from what I can see, although I thought of another way to do this by using MP in place of tp and disabling tp
