Restrict Online R/S to Chiro/Massage only

Have an option to allow online rescheduling by patient for Chiropractic appointments only and not all appointment types as we notice longer massage appointments are harder to fill when rescheduled only 24hours before. So either allow option to only choose chiropractic appointments or to do a different reschedule period for Massage versus Chiropractic e.g. 48hrs for massage and 24rs for Chiro.
