Randomizing weapon animations (resolved)

I have a weapon with multiple animations for the same sequence that I'd like to randomize through via stateShapeSequence, similar to setActionThreads getRandom. I did some searching and couldn't find any similar references, if anyone has a suggestion I'd be appreciative.

EDIT: I've resolved this by setting up additional States; Active > Ready > Fire > PostFire > Ready2 > Fire2 > and so on. Not random, but gives the effect I want (diversity in animation).
