Casting battle animations independently inside combat

A simple example:
There is a Skill where you drain life of the enemy. There is an animation for inflicting damage to your opponent and then
there is some kind of healing animation to show, that you healed yourself.

The problem is, the target is one enemy and only one enemy. I can barely cast animations on my target but this time I need two different information for two different targets.

Is there any plug-in or trick to solve that problem and getting a proper life steal animation?
It's important to know, that I don't want to set pages on the combat Screen, that would be to much configuration effort for every encounter in the game.
