Ability to remove ALG's before they were constructed?

[Rolds]

So this might be quite hard to do, but could there be the possibility to remove some of the beachhead ALG's before they were constructed to show the landing area closer to the way it would have appeared before the allies started building those airfields? The way I imagine this working would be in the mission editor you could click on the airports and where it comes up "Warehouse in Airport", have an option to remove the airfield and replace it by fields and trees.

This might require a ton of work though so please don't worry about it if it is too hard!
