Relisting in bulk from draft folder without making duplicate listings -Oh what a mess I've made!

[laura52497]

Help! 

I  put all my unsold auctions into drafts to save for when I could get to them. They disappeared from my unsold section where I had dates for end of auction and went to the draft folder where all had the same date. I realized then that I had 800 listings that had ended at different times and couldn't tell easily which would be duplicates without relying on Ebay to send me a listing violation for duplicate notice.  My reason for moving them to drafts was I thought they might be deleted by Ebay due to sitting in my unsold folder for so long. Does anyone know a way to tell if listings are duplicates from a draft folder without going thru each one.? I thought of starting over but have so much time invested already and so much frustration. Help please !
