Scroll through animations

Hello,

I have a BP character and want with the pressing of a button to scroll through different animations in succession (Body+Head) and with another button to scroll back. What will be the best way of doing it?
I have made it in the level blueprint, but over there i can play only one animation per time(No Body+Head).
I`m trying to do it with a state machine, but don’t know how to make pressing a key to be a “transition rule”. My character doesn’t do any moving in general, just want to play these animations.

Thanks

Did you ever solve this? Did you think about using a Slider Instead pressing buttons? Good to know. Thank you for a reply.
