Users - Add multiple roles to one user

If you have many boards with different user groups, sometimes user groups overlap. Currently, users and groups have a 1:1 relation. To conquer the overlap, it would be great if it would be a 1:n relation. One user can have multiple user groups and access to multiple boards.

Example:

Boards

• Board A - User Group A

• Board B - User Group B

User Groups

• User A - User Group A - must only see A

• User B - User Group B - must only see B

• User C - User Group A & C - can see A & B

I thought that through with multiple user groups, but that would be an immense overhead if you have 5+ Boards and multiple access variations (A+B, A+C, A+C+D, B+E,...).
