There is a possibility to change the map provider and to import your custom base maps in the Android version of the app.
You can import the .kml and .kmz file in the app which will allow you to use, e.g. polygon that represents the boundary of the area or your custom base map of the area.

You can also try to see if the new feature is documented in the street base map since it can be sometimes more up to date than the satellite.
The map provider for the iOS version is MapKit. In case that the map is outdated we need to wait for them to update them.
