Facade Mission, Set boundries of facade via Manual Mission

For Facade Missions, especially in an Urban areas, it would be helpful to have a feature that you fly a manual mission where you fly to Waypoints to “outline” the top and bottom corners of the facade. This will automatically set the height of building, lowest points, and offset (distance and confirm perpendicular) from building. This would be especially helpful on offset facades and when mapping faces of dams that are lower than where you are standing.
