Every calendar in high level is associated with the contact as the primary object, which it is necessary to have the contact part of the appointment for reminders and notifications, etc. However, when it comes to businesses that may have multiple opportunities for the same contact, for example: home service businesses, where one contact may have multiple properties or job addresses, high level has no way of booking/scheduling these "job opportunities". In this scenario, an appointment for a contact with multiple opportunities, shows up on every opportunity that contact belongs to.

It is also almost impossible to update the correct opportunity from a booking that is meant for a particular job opportunity.

For people in this situation, the only solution is to use third party booking systems and link the data through APIs/automations to connect it in high level.

If there was an "opportunity calendar" where the booking/scheduling was primarily linked to the opportunity itself, instead of the contact, I think this would be a game changer for home service based businesses, or really any business that is trying to "schedule an opportunity" instead a "contact".
