Is there a way to see all existing zones on the map (visually)?

Sometimes I’m trying to open up a module someone else made, and I have to determine what name they’ve given to a zone, but they’ve got dozens of zones. Is there a way to visually inspect a map/board showing all zones graphically? You can do so individually (by opening a zone and choosing to ‘reposition’ it), but I haven’t seen a way to show it for all of them at the same time.
