My apologies for the delay here! At this time, $Source is not an eligible attribute to group or filter by. The doc you correctly referenced on our Supported attributes lists all of the eligible attributes, so custom properties are also not eligible at this time.
I have already forwarded this as a product request to our API team, and I will update the thread if anything changes.
