Comment on Event screen pulling to reoccurring appts

It is currently set up within scheduling when making a reoccurring appointment, that the event number and screen mirror each of the reoccurring appointments. This is great so we don't have to copy and paste the comment on the event screen to each associated appt. If we could make it to where they all copy to the reoccurring appointments, but once the appts are created break that link so we can also edit each appt comment as needed. We currently had a patient coming in for a 3 series injection. We were trying to denote in the comments which injection she was having at that appointment, but when you edit one comment, it applies to all appointments that were made via the reoccurring screen.
