TOPIC: Enhanced Attended button

Would it be possible to have an Attended button which globally checks off all registrants to an event -- or all selected registrants in a list -- in addition to the individual Attended buttons for each registration. This would be extremely helpful for events with a large number of participants, so that the admin can first mark all registrations as "attended", then uncheck only those who didn't end up attending. My client for instance has events with over 100 participants, so clicking the Attended button for each participant individually is tedious. Thanks for considering this for a future version.
