Individual (REDFOR) three-digits callsign selection in MP

[Volator]

As a mission designer you can/must assign a callsign to aircraft in the mission. You can also assign bort numbers for aircraft, but they can be changed in an MP mission in the loading screen. Callsigns cannot be changed.

In order to make use of realistic, individual numerical code callsigns as used in the Warsaw Pact in MP missions (where the mission designer does not know in advance which pilot is selecting which aircraft) could you please add the option in the rearm/refuel screen to also change the three-digits code callsign to have proper interaction with AI ATC and GCI (at least for REDFOR aircraft where pilot IDs are the callsigns)
