Appointment reminders

Please can there be an option for appointment reminders (email and Whatsapp) to go out 48 hour before instead of 24 hours before. Often the reminder can act as a prompt for clients that have forgotten their appointment and may need to cancel or rearrange the appointment. Having an extra 24 hours to offer the slot to another client, especially when working as a solo therapist and completing all admin tasks including booking and rearranging appointments as well as being a therapist. Many thanks.
