"Blend Poses" - how to trigger notifies of highest weighted animation?

Hello! For my game, I have it set up so that the different melee attacks are set in the “Blend Poses” node (the int one.) The issue with this is that as the player transitions from attack 1 to attack 2, the notifies are triggered in both animations, even if attack 1 was already transitioned out of. Is there any way to set this up so that it only triggers the notifies of the highest weighted pose?

Thank you!
