Patient Schedules

We would like to be able to book patients appointments for the following year, but not give them out to the patients until the time is right. So would like to be able to print and send schedules via email to patients, but select the dates inclusively. For example: From Now until December 2022, but we have provisionally booked them in for 2023, but they don't know about those appointments yet, so we can move them about without messing the patients around. Maybe an option to 'hide' certain appointments, even if it's for a whole year! Thank you!
