Not that I'm aware of.

If you use the Seller Hub, all your drafts will be available. All Selling only shows the most recent.

Drafts expire between 6 and 10 weeks. They fall off (for me) on the 16th of the month. If I had any, then all of March's would have gone on the weekend. But 1 April wouldn't go until next month.

You could always schedule them and change the scheduled date as they get close.

If you have Selling Manager Pro, seller hub also has an Inventory function where you can store about 400 listings as templates indefinitely.

I keep all of my pictures until an item sells, and full descriptions in Notepad, so I can recreate a listing in a few minutes if necessary.
