Non-melee computer using spells

is it possible to make non-melee computer to use normal and hero spells?
see...i was making this map with boss monsters, but the only thing the boss is capable of doing is using passive skills, and i want it to be smarter to use active spells.

The only thing they need to use spells is that the spells aren't based in channel , they also have to Have the spell learned, enough mana and cooldown to cast it, and they should feel the need to cast it.

Really? I don't have to give it melee AI or anything?

Sadly, the only way I've been able to get enemy heroes to cast abilities is to give them to them in the object editor, with enough mana... then preplace them on the map, double click and go to abilities. Set the level of the ability you want the hero to have and click the active button. This works for me fine, and they use their abilities pretty often, yet if you want the abilities configured to do something special, they may not know what to do with them.
