Surprised this is not on the idea list already.
We need the ability to have the infill be a yes or no parameter when demolishing a window or door. When a door or window is placed in the same spot, the infill will remain. The only way of getting around this currently is to create a wall in the same place as the door or window and demolish the wall so you are left with an opening. Then you can place a new wall with the size of door or window needed. If we had the ability to select yes or no for the infill, those extra steps would be eliminated.
