After “append” search, view only “unread?"

Hi. Perhaps I’m missing something obvious (or have forgotten), but when one changes a search term slightly and does an “append” search after having read the previously found articles, DA notifies under the start button with something like “Results: 13 of 38 unread,” where the 13 are due to the append. How can I view only those 13 so I don’t have to work my way down the list of all results again? Thanks in advance for your help.

This is currently not possible as you can’t sort by a Read / Unread status. We will consider this for future releases.

That would be awesome, thanks! This was only a small search, but that capability would really shine if someone had hundreds that had bee reviewed and an append search turned up only a few more.
