Linux additional desktops

Something I'd like to raise (or I've completely missed how to do it) is to have a method where where a headless linux server can spin up multiple, concurrent,individual ConnectWise sessions.

EG: Using (as an example) x2go to connect to said server, x2go-session will spin up a users session on the fly - allowing multiple, concurrent users to gain a remote desktop to the server.
ConnectWise seems to be limited to just connecting to the servers actual desktop.
Because in my instance x2go relies on a messy VPN connection, It'd be really good to have the ConnectWise service available for all our remote connections.
