Let limited time creatures be account-wide

So I started over for fun a couple times, and I was here for the Steampowered Pilwiz. For some reason on a couple of the restarts, the guy showed up to give it to me anyway. Most of the time it does not. It would still be possible to phase the creatures out other ways if needed, but would it be possible to just unlock it by account. Making 5 save files and leaving them there just to pick up limited time creatures works, but it’s a hassle and you can’t change your options on those files then. Maybe just have an NPC that lets you pick up all the limited time creatures you were around for?
