Add event registrants to central guest list spreadsheet

Event registrations arrive without attendee context, blocking smooth check-in. Add registrant details into one guest list so coordinators can prepare same day.

Overview

When registrations don't flow into a single guest list, coordinators and support staff lack attendee context and scramble at check-in. This captures registrant details into your master guest list and delivers attendee context the same day so check-in and follow-up happen smoothly.
