Survival Games: Different Lobby Walls?

Is there a way to make multiple lobby walls (yes, I know that's possible, but) with different arenas in them? I've seen servers do it before. I just want TeamVareide maps on one wall, and custom, staff-made maps on another wall, without the walls being connected. Is it possible?

 

SG came out with a beta build recently, and now you can do /sg addwall (arena number). SG hasnt been working for me though, so if it works for you dont mess around with it like i did D:

 

Would this beta build be the 'Dev Build 0.5.0'?

 

I have having the same issue, I have 2 walls and each should fit about 5 Arenas. I tried /sg addwall but it told me command not found. I am on a dev build of it found here (Build #10). I even tried /sg setlobbywall 2 just because I was out of ideas. Please help and thanks, in advance.
