Since my client is set to install via GPO on devices joining the domain, or after reboot, I get devices connected to my ScreenConnect sessions frequently. Unfortunately, I have no way to determine which computers were joined unless I were to make the installer completely blank, but then I would need to figure out what site they were at.
There should be a session group filter option for recently added. This will let us determine which devices recently joined the sessions list.
