Good question. It could be rotatable, or.. It could be a set of standalone action tools located in the structures menu with all the walls - you'd select which side, then select the wall/material, then apply it to the map. I'm not a coder, the visual aspect just really bugs me.. Can't imagine any structure with the exact same exterior as the interior, or a door with a huge indent on the inside and outside of the structure, or an interior floor tile visible halfway on the outside. lol
Plus this way we could have more of "wallpaper" options finally, rather than just stone/industrial walls for everything.
