Location Sharing Map: Allow Selection of Custom Basemap Shared to a Group

Peters_Amy

In Survey123 (ArcGIS Online), my field users need to see their real-time tracks overlaid with project areas where they are allowed (or restricted) from going. I would like to be able to give them a custom project map in the basemap icon selector inside the Location Sharing Map screen. Currently, only basemaps that are shared by an administrator of the organization are there but I need a map that can only be shared with a group, one that the entire organization should not see.

Thank you but I'm actually referring to the maps that are available in the Location Sharing map that is the screen just OUTSIDE of the survey. I need a basemap in there that is not shared to the org, but only shared to one of my groups. My field users need to see their tracks over a custom project map that is internal to one ArcGIS Online group.
