There is a way IRL with our harrier to save "Target Points", As well as waypoints, markpoints and offsets.
Quick access to this menu is the WP Seq select button. Then select the corresponding Target point on the ODU.
However this is still not modeled, and hopefully will be available whenever the JDAM comes I believe what Zeus was waiting for. The only way that I know of to access the Tpoint and save them is with the F10 kneeboard menu load, and to use from the CAS page. Obviously a work around until its fully implemented.
