Timed objectives

[CountryBoy]

I'm in the middle of the Normandy '44 campaign and it occurred to me that it is the perfect candidate for timed objectives, like those that exist in Serbia '14. It would encourage the Germans to hold as much ground as possible, as well as encouraging the Allies to push as hard as possible. I can think of other one-sided campaigns (like France '40) that would also be perfect candidates.

Is there any possibility of introducing them to the other PzC games like Normandy '44, or is it simply not possible due to the game engine?
