Adding Listings to a custom WP/BuddyPress Menu

Hi,

I would like to create a custom BuddyPress menu, but don't find a way to add Listings to it. Listings appears as an empty header in the WP Menus panel, but it is missing in the BuddyPress menus panel. All other BuddyPress components/plugings are selectable, but not Listings.

Any idea how I could do that?
