Assign more than one role to a member

In complex communities, assigning two roles to the same member could be interesting.

Imagine a community with members and students together where they can only access specific channels.

A user could be a member of the community and a student of any course, but we only can assign them one role. Right now, we only can create a third role, "Member-Student," but that complicates everything considering that we might need to change their roles in the future using automation.
