Garmin Explore collections manager - Update 6.30?

The list of changes for update 6.30 say "Added Garmin Explore collections manager".  Can someone explain what functionality this adds?  I'd assumed that I would have some way of accessing my Waypoints as collections on the device but I can't see any changes at all.  I already had my Waypoints arranged within collections on the Explore Website and synced with the Explore App but they only ever appeared as a single list on the 66i.  I've re-synced everything but I still get just a single list of all Waypoints on the 66i.  I've tried pressing Menu from within the Waypoint Manager on the device but no added functionality there either.  The Garmin online manual isn't much help as the last update was January around version 5.50.  Any help appreciated!
