Only the Harrier can pull 'mark points' from the F10 map, as far as I know.
Mark points are something different irl, and are a way a pilot can can quickly create a special type of waypopint/steerpoint from where one of there sensors is looking, Tpod, HTS pod, Helmet, ground radar etc.... and are usually created through the UFC and are limited in number, ie 26-30 in the F-16. They often have extra features like displaying MGRS coordinates as well as the normal lat/long.
Could you associate a bit of text to display as a message along the top, linked with the random event that displays a general location of that event, that the pilot can enter into there nav system as a waypoint to get them on station?
