Can I copy and paste doors and windows?

I have a map I'm adding walls to. There are a LOT of little cell like rooms along a corridor. For added fun the corridor is at an angle so each door has to have its corners individually moved (unless there's a rotate option I missed). To save me going through making forty plus individually arranged little doors is there any way to just select a door or window you have created and copy paste it to make a new one? I haven't gone through all the tutorials yet - still working my way through them - but am trying to prep a game.

Thanks for any help even if it's confirming it's not possible.

No, there's no copy/paste facility for adding occluders.

A shame. I'll add it to the Feature Requests if it's not already on there as this would be a very useful feature to have. Thanks for confirming.

You could make one door in its own layer and duplicate that layer. Same with lights.
