Hi Dave,
It is not a possibility to transfer saved listings from one Auctiva account to another so, unfortunately, you will have to recreate your existing saved listings in order to use them for your second Auctiva/eBay account.
If I am not addressing your question properly, please file a support request using the appropriate link on our help page:
