This may be a silly question but I'm making uppers for a laundry room, 4 doors across. I originally had a one door left swing, a two door with handles in the middle and then a one door right swing. But my boss said it would be better to make it all one cab with 4 doors. I am not seeing an option for an upper with 4 doors....Isn't there a place where I could add as many doors as I wanted?
