Hi suesade,
While you cannot create a saved listing from an active listing, once that listing has closed, you can import that closed listing to your saved listings folder in order to revise and repost the listing. To accomplish this, please go to Auctiva -> Listings(tab) -> Closed, check the box next to the item, and click the blue "Import" button.
If you are looking to add an Auctiva template to your listings that are already active on eBay, you can do so via the following process:
1) Recreate the listing in Auctiva.
2) Once you have finished, click the "Save" button.
3) Return to your Saved Listings page, check the box next to the item, and click the "Get HTML" button.
4) Select All and copy the html in the popup window.
5) Go to the item that is active on eBay and click "Revise Item" then "Edit Description"
6) Click the "Enter Your Own HTML" tab above the description editor.
7) Delete the html that is already there and then paste the copied html in its place and save you changes.
