How do I block animation inputs for certain characters?

I have a setup where two characters are on screen. I just finished the parts needed to switch between them at will and everything works as intended.

The only issue is that both characters continue playing their walking animations after switching between them (or in this case just changing the direction they're facing). I am using keyboard inputs for this.

Is there any way to prevent character 1 from playing any animations, while allowing character 2 to do so and vice versa when switched? Thank you! Screenshot attached.

I fixed it by adding a variable requirement to the keyboard events that are linked to the animations, but let me know if there is a cleaner way to get to this point. Thanks!
