Combine character blueprints?

I downloaded from the Unreal marketplace two Blueprint setups. One called “Footsteps Sounds with Blueprints” and “Custom Movement.” But there is TONS of info and extra functions in each blueprint for the player character in each one. Plus, the player character BP has other BPs it’s lnked to as well… Is there some way to combine them both? I copying and pasting the contents of one character BP into the other, but there were tons of references that didn’t go with it. Please help!

You can change the parent of one of the actors in Class Settings of the BP, it can still be messy but I think that should do most of the job.
