from @Brad_Brockman on ST community forum - allow devices to grouped for rooms

[adey]

and enable a way to show them as a list similar to the grouping of devices that rooms in ST allow.

I'm not sure what this request is actually meaning, but I'd suggest this functionality is best left to another smart app. Try kriskit.trendSetting: group Group your lights outside of Room Manager and use the group in your Room configuration like any other device.
