You could use autohotkey to acheive it, though. i.e. change the action of a keybind based on whether or not right mouse is down.
You'd have to check the game's TOS to see if it's allowed, though.
These are the binds I have been using for a few weeks that I play really well on. The building feels really natural.
It might help someone out.
Edit and weapon slots are bound to my mouse.
