When setting up an automated Reminder to Book campaign, we want to be able to filter the types of clients that the message is sent to - not just to all clients in our system. We have Botox clients that need to schedule 3-4 months out, compared to laser hair removal clients who need to come every 6-8 weeks or aesthetic clients who need to come in once a month. This feature is unusable if we are not able to target specific groups of clients.
