How would I make a save game recognize specific variants of the same Blueprint?

So I’m wanting to make a collectible system that works something like the Music Notes from Banjo Kazooie,which is each level has a finite amount and the save game recognizes which ones you’ve already collected. I’ve already got a save system up and running, but I was wondering how to implement this without having to make a ton of individual blueprints and saving each individually? Maybe some way of saving and recalling a specific instance of an actor?

Thanks!
