Attendance Statuses

We have custom attendance statuses for our clinic to be able to determine appointments cancelled by a patient (and whether they gave notice in advance or last minute) vs. an appointment cancelled by us due to a sick provider, holiday closure, etc. I feel this should be part of the default options for ClinicSource as appointment reminders still go out for custom attendance statuses but not for the default "Cancellation" status already coded into the ClinicSource software
