Change # of Group Attendees when Scanning with QR

Hi Tuan,

I was wondering if there was anyway to adjust the numbers for a group registration when we scan their barcode off their registration? Or if there is an ability to add another form field for additional guests?

I don't need to subtract from the total, only increase based on added attendees.

Is this possible?
