Make it possible for an admin can add attendees to an event in Almabase after the event has taken place.
We don't have email addresses for all of them, but do have names.
It is important to be able to add attendees post-event so that when the data is synced with RE to reflect who attended the event, the additional attendees will be reflected.
Overall, an option to add guests without an email, during or after an event will help.
