If you make a double-door, using 2 doors, you can change the orientation of the door. Breaking the unwanted door leaves the wanted door in the orientation it was in double-door status! Make sure you put the second door on the side that you want the handle to be on!
Used these doors cause they show direction easier. Left is default placement, middle is double doors, right is after making the double doors and removing the extra one. Hope this makes sense!
