Custom Defined User Selection Cap

The web console seems to have a loading limit of 50 users cached before you have to scroll to the bottom to trigger more Users to load. If a client has 1000s of mailboxes for example and only needs to backup specific ones, the 50 limit takes some time & scrolling to get everything loaded. A current Partner would like to see a type of selection for the number of items cached (users or workstations) such as [50 (default), 100, 200].
