We are running into issues when the export from Hi Rasmus doesn't include all of our sessions, we don't bill for them, and it is very difficult to track this down. It would be a super awesome helpful feature if there was a way for select people to mark appointments that have been exported and sent to billing and then another way to mark them as paid once they are paid. I don't mean with the amounts and rate schedules, just a mark to indicate both of those steps have been accounted for.
