Scanners Highlighting Add On Customers

It would be fantastic if the scanners highlighted customers who had purchased add on products. We offer a car parking ticket which requires physical pick up. We've moved this from 'Collect at Box Office' to Event Hub QR coding, but customers are forgetting to pick them up and getting stuck at the car park and therefore paying twice.

If it could flag the customer has purchased one on the scanner then the ushers would be able to hand them out, rather than being reliant on the customer to present the QR code. 

Similarly to the First Time Customer marker, if we knew customers had add on products immediately and obviously upon scanning we could also give them instructions on location of collection points when they arrive, etc. 

Thanks!
