Is it possible to create our own working doors

I don't believe they have added the function for custom doors, yet

Not yes as @angriff said but it is planned if I remember correctly. ( @red51 maybe could confirm or deny this?)

I remember a door opening routine in the API script also ,, wonder when that will be put in?

Hope that Red does get this into the game having made many custom doors/gates with pnb this would be a great addition to the game.
