Kali-win-kex, change fullscreen across monitors mode from the commandline?

[mrcrabs]

Hello, does anyone know if there is a way to toggle fullscreen across monitors option on/off in kali-win-kex from the commandline. I'm trying to automate my current process for switching from dual to single monitor so that I don't have to go to the options menu every time I want to change the displays, and I can't seem to find any information about this.
If anyone can shed some knowledge for me. I would be most thankful.

If you start kali-win-kex by executing "kex" you're running actually the /usr/bin/kex script.
The script is launching /usr/lib/win-kex/win-kex with :
-FullScreen=1
by adapting the /usr/bin/kex script you can change that behaviour.
Executing /usr/lib/win-kex/win-kex help gives a full overview off the available parameters.
