Printing Multiple Copies Of Specific Qr Codes

Hi Tim. We are photographing a dance studio. In total - 314 dancers, however many of these dancers are in multiple dances, so there are actually about 1000 costumes. Because it's a busy day and we are photographing children, we feel it's important for the dancers to have one QR code for each dance they are in (in case they lose them when changing etc). Is there a way you would recommend we efficiently print the correct number of QR codes needed for each dancer?

I'm sorry, but I don't understand the question. 

Seems you would want the dancers to have only 1 QR code each so they can enter that and see all of their photos.
