Need easier permission administration

The permissions view currently in confluence is from a resource. It would be VERY convenient if it was from the viewpoint of a user or group.

Today, it is "show me all users/groups that have access to this resource and their permissions".

We also need: "show me all the resources this user/group has access to and the permissions on that resource"

This would make it easier when adding a new user/group. If I have 5 spaces that user/group needs access to, I currently have to do this 5 times by visiting Space Administration for each space and granting permissions to that user/group.
