Ground Attack unrealistic for medium bombers

[CzechTexan]

This may have been covered before but I thought it should be brought up again, if it has.

The problem I have is with medium bombers (A-20, B-25 gunships) and their repeated attacks against ground targets.

These repeated attacks are unrealistic - especially if there is heavy flak. Whole flights get wiped out by repeating tacks on targets with heavy flak. Realistically, one attack would be made and then get out fast and head for home - not only to avoid flak but also enemy aircraft.

Is there some way that the A/I behavior can be fixed?
Is it possible to make an option in the FMB for Ground Attack where the builder can choose to make only one attack run and then head for home?
