Add Select All in the Edit User form

Currently on the Edit User, in order to give either edit access or view access, we use the option to "view workspaces with set permissions" which shortens the list to only the product line. We have currently 35 product lines and will continue to grow as we bring on other teams. It would be great to have a "Select All" that would systematically select all product lines and workspaces. We would then manually deselect the few product lines we don't want our folks to access.
