Display a dynamic polygon from an external source on the map?

Is there any built-in feature to draw a polygon on the map from an external live source that changes rapidly? Something like the KML overlay feature (right-click map in Plan -> Map Tool -> KML Overlay) that can change dynamically.

I am fine with implementing whatever protocol is needed to bridge between Mission Planner and the live source, I just prefer to avoid modifying Mission Planner itself.


You can do it with a plugin.
Host.FPGMapControl and Host.FDGMapControl are exposing the FlightPlanner and FlightData map control in the plugin class.
