Ahh, ok. I didn't see it as part of the listing process when I tried to post manually on eBay and that's why I couldn't find it.
Since this is an account setting on eBay, I'm surprised that posting through Auctiva is making a difference. Usually account settings don't need to be passed along with the info we send when posting an individual item.
I'll check this out and see what we can do.
