play animation forward or backward to a specific frame?

I have a model mechanism that has a lot of IK in it. What I want to do is create an animation sequence that encompasses the entire range of movement and then be able to play the animation forwards or backwards and stop at specific frames to set the position of the model as desired. The stopping frames are set dynamically. Can this be done?

You could try using Anim Notifies. I don’t know if it would work but they’re basically keyframes that talk to blueprints and are used for things like creating dust particles when your player’s feet hit the ground and/or sounds etc. So with that in mind you could try using those along with blueprints.
