Generate Feed File on Existing Listings

Does Amazon 3P offer a way to create a new feed file based on existing’s ASINs in your catalog?

on 1P, we can select the specific child variations from our catalog and it will generate a beautiful completed feed file for those units where I can easily make changes. Does 3P have something similar? I know you can manually add ASINs in the “download a spreadsheet” page but those fees files typically only include the child ASIN and product name…

Thanks!
