war base update button/village update button

I would really like to see a button added in the war base editor that would allow the base to be reset to the current village layout. Having a separate layout is great, but at times when extensive remodeling is done to one (like after a TH upgrade, wall improvements, or even just the urge for a new layout) it becomes extremely tedious to duplicate. Having the button in the village editor to reset village to the war base layout may also come in handy, as people develop a new defensive strategy in war that they would like to implement on their home village
