Wrong Flags when Airfield is blue or red

[ex81]

I declare an airfield in Iran as captured and place Units on it.

But it looks strange, when there are still iranian flags moving in the wind.

 

Why can`t it be, that the flags change to the nations one, which is holding the airfield.

 

There could be a way to place different flags in the ME.

 

would love to see a chance doing this.
