Hello again,
I just wanted to follow up on my previous post to this thread to let you all know that we actually did add the ability to bulk revise active listings through Auctiva. If you would like to see what can be revised using this new tool, just check the box next to an item on your Active Listings page and click the "Revise" option.
The shipping insurance section is not one of these but I suspect that may not be necessary depending on how eBay handles active listings. I am trying to figure out how active listings will be affected once this new policy is implemented and I'll update this thread with that information if I can get it.
