When sending sms reminders you can filter by individual appointment type but you can't exclude an appointment type, which is what we'd like to do. We are a physio clinic and have 8 appointment types. We would like to send a reminder to all but 1 of these types (our exercises classes - which are at the same time every week). Currently the only way to do this is to filter by appointment type 7 times and send out to 7 separate groups & NOT send to group we don't want. If there was a tick box next to each appointment type & you could choose which you wanted to send to this would be extremely helpful.
