New Feature. You can allow users of a uAttended key to access all descendants of that type by selecting the "uAttended unlocks children" option below. This is turned off by default, but if selected on an event type that has at least one child, a icon will appear next to the code on the list of event types. You could combine this with a virtual event type where you could enable access to a parcel of child events to selected administrators.
This works automatically on the site, but, for now, will require a user to log out and log back in to show newly unlocked descendants in the uAttended app.
