[Organizers] Tracking/Tracing Venmo Payments?

Hi, We've been trying to figure out how to tie admission payments via Venmo to specific events. I'm not the account user so I'm only hearing this second hand or through web search, but we can create QR codes in Venmo with information encoded in them, e.g.: https://www.paypal.com/qrcodes/venmocs/be7ee836-3a9a-44c7-94e3-d6a1ae93b6b9… But I'm told when they are scanned, folks still need to key in the amount (despite it being encoded in the URL). And when payment comes through, there is no tie to a unique code that makes for easy attribution to a specific event. Are there any tricks others have found for doing this? It would be great if we can separate generic donations to our organization from event admission payments so we can properly credit them. This is something easily done in PayPal but folks don't seem to have the patience to use that tool and have asked for Venmo availability. Thanks in advance, Don
