Need button held for an Attack Stance, but stop at end of animation and wait for player input.

I am currently trying to have an attack stance play when an input is being held. While the input is being held, the attack stance should play once and wait at the end of the animation for an input by the player to attack. I cannot get the animation to pause at the end of the attack stance.

Any ideas?

Here’s a gif of the current issue.

And here’s the current BP. We have the current input down as LockOn (spacebar) in the Player BP, so when pressed it’ll play the animation (currently a montage), and when released it’ll go back to our idle animation, which is currently set up as a Blendspace in the Animation BP…

Thank you
