S&R feature request, "Pin Drop"

For search and rescue, anti-poaching and other similar operations using Mission Planner there is a fairly critical need to have the ability to drop a 'pin' or a POI on a specific point on the Flight Data map with easy stored access to it's GPS coordinates.

We have the "Fly To Here" option but how do we get easy access to the GPS coordinates of that position, apart from the coordinates of the mouse pointer (which moves obviously)?

A "Fly To Pin/POI" option is also needed here.

Another use for this is the recovery of a downed aircraft, dropp[ing a pin on it's position (or last known position) with easy stored access to the actual coordinates so that they can be entered into a standalone GPS.

No files, tests, or entry points are named. Review the Flight Data map and existing “Fly To Here” behavior first; done means a selected point can be stored with accessible GPS coordinates and can support a “Fly To Pin/POI” action.
