Is it possible to tie an animation to a slider bar or progress bar?

I have a client that wants to be able to play an animation that can be played, rewind, and scrubbed with a slider bar on the UMG. There must be a way to do this, im just not sure how.

Yes, it is possible. I just answered this for someone else: https://answers.unrealengine.com/questions/1035528/view.html
