I created a screen flow to create records by importing from a csv for event attendees. We have barcode scanners that we use to capture badges with upc's/QR's that contains the attendees salesforce account ID. The output of the scanners is a csv containing a column of ID's. In my screen flow, I have an apex action for importing csv's to a colletion variable. I'd like to put a lookup field in the screen flow for the user to find the event, and then have the flow append the event's ID to another column for each of the account ID's in the collection variable created by the csv. Is this possible?
