Swapping between 2D Flipbooks in Sequencer

Hello, at the moment I am trying to animate 2D sprites moving in a 3D world, using the sequencer. I can get the sprite to move around in the world using the transform tool, but now I’m trying to figure out how to go from one flipbook animation to another, to use different animations for my character. Currently I have a PaperCharacter with the Idle Animation Flipbook assigned, and I want to be able to swap between others, such as walking.

Any help would be greatly appreciated.
