Suggestion for Door Mirroring

Wanted to suggest a solution to a problem that's bothered me for ages. Doors need a mirroring function. Not all doors are the same on both sides, and which way a door faces matters to a competent designer. A prime example is the dorm door that came with University. Has an emergency route map on the inside.  It should open to direct traffic flow toward the main exit, but depending which side it's on, it can't do that while still keeping the map on the interior where it belongs. With the peephole, the door would be perfect for apartment building except this one flaw. If doors had a mirror function, their inside and outside textures could be reversed. Quite a few doors would benefit from such a feature. Gates too. The Timber Log Gate is different on each side and mirroring would let the player choose which way it goes to best suit the build.
