This forum is closed for new topics. However, you can still search for a solution in the old topics. For technical support related to the Nearby Posts premium extension please open a new premium support ticket.
If you are referring to the map markers of the Nearby Locations add-on, then it is not possible at the moment. Not out of the box at least. Premium Settings add-on is not yet compatible with Nearby Locations add-on.
However, I already provided another user with a solution by editing a plugin core file. I think you can use that solution as well until it will become part of the plugin.
