Give photo review discount for specific vendor stores

Dear Sir/Madam,

I’m using Dokan to create a multi-vendor fashion store on my website (https://meadorafashion.com/).
I’m trying to auto-generate a coupon that can be used by a customer only on the vendor store where the initial product was purchased.
The purpose of this is to drive repeat sales from the same vendor store. Is this feature currently avaialble in photo reviews, or else, can this be developed?

Thanks
