Hi,
Yes, you can create the listing as a Saved Listing or Import closed listings (from the Closed Listings page) to Saved Listings. Once the listing is created or updated with a template, you can either submit them from Auctiva or use the <HTML> icon for the listing on the Saved Listings page and copy - paste the HTML code to eBay's listing / revise listing editor description section in HTML mode.
