Thanks for posting your question here. I'm afraid that we still do not offer any functionality that allows sellers to link items which have already been posted to consignment items, so it will not be possible for you to associated these items you relisted with consignors in your Auctiva account without ending and reposting them.
In order to link an eBay listing with a consignor in your Auctiva account, you must check the “Is this a consignment item?” under the description editor and make the desired association there when creating the listing through Auctiva.
If you post an item in this manner and it does not sell the first time around, you can relist the item using the “Bulk Relist” option on your Auctiva Closed Listings page and the association between the listing and the consignor should remain intact.
If you need any further assistance with your account, please feel free to contact our customer support team by mousing over the “Help” tab within your account and selecting the “File Support Case” option.
