When I tried the use the FLOORPLANADD command to copy my "Basement" file to a new sub-basement level ("Basement 2") using the "Copy below" button (to keep my dirt "BACKGROUND" sheet) the new level was created and the keys on the other files were updated but the name of the existing file was not changed to "Basement 1" and its key wasn't updated. I had to make the filename and key changes manually. Is this a bug that can be fixed?
