Do you mean put choice in map menu? If that’s what you mean, for now the map menu only displays your location. So when you open the map, it only shows a marker indicating where you are.
if you want to add a selection system/chooce to the map, you can edit the script for that map plugin.
I hope my explanation helps. And it’s okay if you have questions, that’s normal, and I understand. I’ll do my best to answer your questions.
