Hey @e4deal
Thanks for contacting support.
I first want to mention that 70,000 products is quite a lot and we generally only recommend users with ~10,000 listings to use WP-Lister. In some cases we have seen users with far more listings than that run into performance issues that caused other issues. We typically recommend 10,000 +/- some depending on the server.
With that said, you can assign a listing profile to multiple listings in bulk by using the bulk action drop down menu on the “Products” page of Woocommerce. Select your listings, then select the “List on eBay” option click “Apply” and select your listing profile.
You could also click the “Screen settings” WordPress option in the top right hand corner of the “Products” screen and increase the number of products you wish to show per page.
Unfortunately this cannot be done via an import with a CSV for example. CSV only deals with product page details. We are hoping at some point to offer a CSV plugin specially for WP-Lister which could work details like listing profile options but at this time there is no ETA on something like that.
Kind regards,
John
