Generate Unique item on Store purchase

I am currently using the wix store features and i noticed that it only gives 2 options: Digital Purchase (where you have to set the file to be downloaded) or Physical.

I wanted to add some items that dont really have a physical object like a raffle ticket or like membership fees.
In these cases id want the customer to receive some type of unique item to indicate different purchases instead of just sending everyone the same item (since this could be duplicated and would be harder to verify).

Is there some way i could send the user a uniquely generated QR code or something for each instance of the items purchased.
