Private 4 Player Fog of War?

Is it possible to create a private 4 player fog of war game? I want to play 4 player fog of war with my friends but it is difficult trying to join the same game. Two of my friends play on the same network too, so Chess.com won't allow them to both be in the same game online. 

In the 4 player section of Chess.com you can create your own game, add variants, and invite others or bots, but fog of war is not given as a variant option. 4 player fog of war is in the Variants section, but you can't create private 4 player games in the Variants section. 

You can invite a friend to play 1v1 on any variant, but the Variants section doesn't give an option to invite friends in 4 player games. This includes Chaturaji (I think I spelled that right) and 4 player fog of war.  

Is there anyway for me and all of my friends to play 4 player fog of war? 

I don't think there is, but very few people play it, so if you all have the same time control you should be put in the same game.

The problem with that is two of my friends are on the same network (playing in the same house), so they can't join the same online game. Chess.com thinks they are cheating. It has to be private for both of them to play.
