Hi!
Yes, this is possible to do in bulk.
For Active listings on eBay:
Go to your Active listings page on Auctiva.
Check the box next to each listing you need to revise.
Click the "Bulk Revise" button (below the Active Listings header)
Select the field to edit from the drop-down menu on the next page.
Choose the new handling you want to insert into those listings and click Continue.
On the next page that shows the listings to be revised, click the button to confirm your changes.
Revising your Saved listings is a similar process--go to the new Saved Listings page, choose the listings to revise and click the "Advanced Edit" option. The steps are the same as noted above.
Happy Selling!
