User Administration - View & Edit User Selection for All Activity Permissions

How should it work?

We'd like to have the ability to set a baseline list of users that someone can view and edit and then select what modules we'd like them to be able to view and edit this user subset for.

For example; we'd like to be able to select a list of users at the top of the view/edit columns, then have a checkbox next to each activity permission that we can check and, finally, an 'Add Users' option next to a selected checkbox allowing users to add more than what is pre-selected at the top of the column.

Why?

At this stage, if we have someone at the branch start we need to update the permissions line by line for at least two users at the branch (BM & Admin) to include the new user.

Who would benefit?

Anyone managing user administration in the system.
