Reusing Animation Events for different functions

Hey folks, I'm using animation events in Mechanim to trigger code. But is there a way to reuse the animation/event but change the function it calls?

For example I might have Red Wizard and Blue Wizard with the CastSpell animation, and both have a CastAssignedSpell function called via an animation event

However if the animation played for one Wizard game object and the event happened, BOTH CastAssignedSpell functions get called.

Is there a way around this without having to make copies of the animation for each pallete swap enemy?
