Automatic sick leave notification

It would be very helpful if there were a feature that allowed self-employed individuals or employees to automatically manage appointments when they are sick. For example: Clients would be automatically notified if an appointment is canceled due to illness. Ideally, clients would be immediately offered suitable alternative dates to choose from. Optionally, available times from other employees could be suggested. Especially during stressful times of illness, this would save an incredible amount of time, stress, and organizational effort—for both studios and clients. Additionally, communication would be significantly more professional and straightforward. I think this feature would be a real value-add for many users. Best regards
