How to set AFV facing to avoid flank shots.

[Champagne]

I realized the need for me to be able to set my AFV facing in one direction in order to avoid the nasty surprise of having them show a flank in response to fire from the Computer enemy.

In response to Computer fire during the Computer turn, my tank turned its flank towards a known enemy AT gun and was destroyed when that AT gun fired.

Is there some way for us to SET the covered arc of our AFVs so that they don't do this? We don't want our tanks to turn their chassis to the side to respond to rifle fire when that known AT gun to the front is waiting for that flank shot. Thanks.
