Hello, mods. I've got a question regarding CRAU: What if they have CRAU memories from two games? Would those sort of CRAU characters be allowed?

For Lucy/Nyuu here, they were already Futurology CRAU when applied to Prismatica. I was hoping to app them as a CRAU from Prismatica, but could they still retain their memories from Futuro, the very first game, as well? Or are they only allowed to have memories from one previous game?

Hopefully I'm making sense, but if not please tell me.
