How to easily organize sold listings

Im running into the problem of optimizing large amounts of listings weekly.

I want to end and relist the unsold listings in selling manager, but find that theres no quick way to define active unsold listings.

When I had lower sales it was easy to remember which listings had sold and such.

Is there a way to display only your GTC listings that have not sold? I find its a major lacking feature as far as I can tell.
