Attached Detail Group Members

Is there a way to get the Members of a Attached Detail Group?
I know it is possible for Model Groups.

Bump :upside_down_face:

So i have a Model Group with an Attached Detail Group attached to it.
When i select the Model Group i want the Detail Items Families in a list.

NB
I know you can get the Detail Item Families from a Detail Group with Group.Members,
but not when that Detail Group is attached to a Model Group.
