Add the current Return location to the Teleport menu's History and Favorites tabs, add an icon to indicate that a location in the Teleport list is your Return point, and allow Return to be used from the Teleport menu.

Teleport Menu is basically the one-stop shop for all world travel needs, and having Return stuck off the side as its own totally-separate thing is logistically awkward when it is basically just "Free Teleport with a Cooldown".
