Hi,
I didn't realize that the team forum was still used and neglected looking here for years. Because we couldn't update ShopShaper for a long time, only a few user needs could be met with the features it had and they contact us via email if they have a problem. Sorry about that.
Finally (!!) the new version is out. All users, old and new, can use it for free for a week to see if the current version is the right tool for them. www.shopshaper.net
With the new version it is possible to copy listings in bulk. Please visit the "Help" page to see the how-to guides.
