I had a question about whether the way role groups in DNN works correctly. I don't see a way to assign a permission to more than one role group. Is this correct?

This doesn't seem to be correct because say for example I have a role of edit and I have a couple role groups such as admin, editor, viewer. In this scenario I would want the edit permission to be included with both the editor and admin role group. Can this be done? I don't see a way to do this.

Any ideas?

I did see that that is how it works since I looked in the database and saw that they are just a grouping but I was just wondering if this was by design. It seems pointless since all it does it group them. I would like to use it to group multiple roles together so that I can assign at once to a user using the role groups. Maybe a change for a future version?
