Re-listing an item after 30 days. (Seasonial Items)

[mulhe.aun]

Quick question

If I go through all the trouble of creating a posting (photos and research) is there any way that I can save this for a layer date?

I have a lot of seasonal items that I want to re-post at a later date but I don't want to re-create the entire posting every time I decide to re-post it.

Is there any way I can create (ahead of time) listings but not post them at that time.

I have a lot of items to sell, but I only post 20 at a time for 30 days each.  While I am waiting for those 30 days, I would like to be able to create the next 20 items and just wait till the first 30 days is up so I can post the news items.

Thank you for any help that you might be able to provide.
