Feature Request: Polygon for Map Fetching

@Michael_Oborne Hey Michael. I’m taking a look at the mp code and trying to figure out how to use a polygon instead of the ALT and drag method for delineating the area I was to prefetch maps for. If you have any tips on the simplest way this could be achieved i’d appreciate it! And if there is anywhere else a feature request should be posted I can do that too!

Also - if anyone else has any input for how to modify this I’m all ears as well. Cheers!
