Currently, when adding list members to the "Write" or "Read" columns of a Role's selective access, you need to individually open each "+" and search the entire list hierarchy to find the desired member. The window should include 1) a magnifying glass search button so that the Workspace Administrator can search for specific members within the list hierarchy and 2) an "expand" button which will open up all collapsed nodes so that the entire hierarchy is visible instead of only parent members.
