Can Matinee be backed up/loaded outside of the level they're in?

I’ve been trying to work out a workflow for curating my cutscenes, and since my script ultimately calls for dozens of in-engine cutscenes throughout the game, storing them all as active matinee actors loaded into memory isn’t feasible. Is there any way at all I can save finished matinee sequences somewhere in the content browser, and rig up a central cinematics manager to load/unload cinematics on demand?
