How to play 2 animations with different slots but overlapping bones in AnimBP?

Hey thanks for helping me again!

My goal is for the guy is to play the punch left and right loop with left click held. Then on right click, play the waving animation.

So the issue right now is the waving animation is overriding the punching montage. Where when the punching montage is played, only the left hand is punching, and the right hand (from clavicle_r forward) remains stationary.

Yea I know haha, I’m just doing this as practice.

So slots simply can’t have overlapping bones? What system would I use if I wanted to play an animation from the spine_01 and up, and another animation from the clavicle_r and up?
