Add new roster rows to training event attendees

Your training roster rows go unread, leaving instructors without complete attendee context. Lists become accurate so coordinators can finalize seating ahead of the session.

Overview

Rosters added to a shared sheet often don't make it onto event invites, forcing coordinators to reconcile lists at the last minute. This flow bridges the gap by turning new roster rows into calendar attendees, so room setups and materials are finalized ahead of the session.
