How would i do so when a verified vendor makes a listing it becomes verified
I think there is not such option to do it so far. I agree that it would be very useful.
Unfortunately, there’s no such feature, it would require a custom implementation. If customizations are required for your site, please try customizing it using the collection of code snippets Search · user:hivepress · GitHub and other developer resources, or consider hiring someone for custom work https://fvrr.co/32e7LvY
