If the "Add Attendee" button is what tells Redtail Seminars that the contact should be included in the ATTENDEES count, how can I indicate in a contact’s account that they were invited to the event and not include the invitees to the ATTENDEES count? Not every contact that is invited actually attends. Not every contact that registers to an event actually attends. There should be differentiation/distinction between these, and a quick summary/count should be available in Redtail Seminars.

Is there a way to add a new field/column/count that will show INVITED (separate count/list from attendees)?
