Set a specific amount of featured items per seller

Is there a way that I can set how many featured listings a costumer can have at one time?

Example is I have customers pay for 15 listings but I want them only to have 1 featured is there a way to set that?

Unfotunately there’s no way to restrict this in the current Paid Listings version, if you enabled the payments in HivePress/Settings/Listings/Featured for Featured listings then vendors can make every of their listing featured if they make a payment.
