PLEASE add feature to move terrain overlays below coverage areas!!!!

[Logan.McGuinness]

I often will grab high res screenshots of site aerials from Google Earth and bring them into IW as terrain overlays as a quick way to improve ground imagery in a small area. Or photoshopped site plans from an architect to depict proposed design. I'm against such tight deadlines that I honestly do not have time to go through the process of geolocating ground imagery or figure out another method. Problem is, all my coverage areas are then covered and there is no way to move them on top. PLEASE DEVELOP A WAY TO MOVE COVEREAGE AREAS ABOVE TERRAIN OVERLAYS. THIS WOULD SAVE HOURS OF WORK
