Anybody know if it will be possible to have units fall back facing the opposition in MTW2?

It has always been an annoyance to me that it hasn't been included in the previous games. I have lost count the times I have wanted to give ground to allow troops to flank or encircle an enemy. Whenever I have tried this I have had my troops turn around and walked away getting hacked down as they do so.

I used to think that it was just me being incompetent however I now know that it was never coded.
