Featured Package Offered as Upgrade

Hello Good GD Folks,

I’m wondering if it’s possible to create a package for Featuring a Business Listing after the listing has already been purchased and running for some time.

Say they buy an annual package with no featured listing, but three months into their contract, they decide that they’d like six months of a featured post…is it possible for a package to only show on the Add Listing form AFTER they already have an active, paid listing?

As it stands now, they have to purchase a 6 month or 12 month boost for featured listings when they sign up for the annual contract.

Thanks!
Ashley
