AD Sync Devices?

According to Sophos Central What's New 24th June "If you use our AD Sync tool, you can now synchronize devices (computers and servers) and device groups as well as users." This is something we've long wished for.

I have AD Sync 3.1.11 which appears to be the latest, but I can't see any sign of Device configuration, e.g. I was hoping to find Device Discovery Filters.

Has anyone tried this yet, or found any documentation on how to add devices into an existing AD Sync configuration, or is this so new it's not actually there yet?
