[Events 2.0] Ability to add or remove a guest to/from a registrant

It would be nice if I could edit a registration to cancel one of the two or more attendees that registered for an event.  I have a party that an employee registered for themselves and a guest to attend.  At a later time, that employees reached out to say that the guest was no longer going to attend, but the employee was still coming.  I can delete the name of the guest, but I can't delete that second entry, so the total number of attendees that the system tracks is inaccurate. . .   not critical, but I can't rely on that number, I have to keep track separately.
