Hello, here is an idea. If you have a listing with an error how about
Being able to upload all other auctions except the one with the error
or
Being able to EASILY identify the auction with the error. I had 600 auctions going up and 1 single auction did not have a pic. I could not for the life of me find what the faulty auction was! Maybe present a list of the faulty auctions and be able to click and easily modify them so they can be uploaded.
