In the Paid Listings extension, is it possible for vendors to upgrade their existing paid listing to a featured listing? For example, if they bought a listing as an ordinary one, can they later choose to pay a fee to upgrade it to have a “Featured” status? If not I would like to request this feature.
Unfortunately, there’s no such feature, it would require a custom implementation. They can buy a package through Paid Listing when creating an ad, and if the Make listings featured feature is enabled in this package, then all listings will be featured accordingly.
