Timer for Screen and Hold

[DIVM]

Hi, I had some ideas for Features Requests, I'll do my best to separate them in different threads to make them clearer.

First one: I wish Screen and Hold had the option to have a duration timer. That way we could set different SOP at different times without having to manually wait for our next command cycle orders to make them manually. Very useful for things like:
-Taking over a new area that you think you cleared but aren't 100% sure, you would like to have the unit in a Screen status and withdraw quickly if fired upon (Relocate when Receiving any fire, Fire Discipline to Point Blank) . However, after say 20mins, settled in and Hold and do not withdraw (maybe awating a counter attack), with Maximum Range and Do or Die.
-Units defending a pass that you know the enemy will have to cross. You might want to have a Hold status with Short Range fire discipline to let them in and attack by surprise, and later shift to a Maximum range once you know the enemy unit should've been already attacked or passed your ambush point.

I guess these SOP could be implemented as "IF X then Y" kind of automatization of SOP changes, but I guess giving timers to Screen and Hold is a more realistic request for the short term?
