It would be so incredibly useful, especially for clothing creators, if there was a column on the marketplace "manage listings" page that showed the item selected as the demo for that item. We currently have no way of double-checking that the correct item was selected without editing every item and looking at them individually. (When doing tons of listings, it is easy to accidentally select an incorrect item as the demo.) It would also be great if we could assign a demo to all selected items during the bulk edit process. Usually all color variations of a clothing item use the same demo.
