Hi kryptoknight,
Well...you can add Auctiva templates to listings you created throgh Turbolister, however, its a fairly cumbersome process that involves basically recreating the listing in Auctiva. If you want to give it a try, you can accomplish this by revising each listing via the following steps:
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.
I hope this information proves useful.
