Feature description
I'd like to suggest an addon to have different advancements per group.

How the feature is useful
My friends and I love separating our server into survival, creative, and manhunt. If advancements are separated with it, we could keep the aspects of survival minecraft in one world and keep an essential part of manhunt in that world.

I'm closing this as a duplicate of #340. There is a test build available in the last comment of #363 with this functionality.
