Hello Gui,

Thank you for reaching out to us.

Events are separate entities and customers can not reschedule event since events can not be rescheduled via custoemr as services only admin can do this. So they or you need to cancel the appearance of that attendee and then to book or add them to a new event. 

If you are rising a services you can create fixed work hours for that service in employee work hours and you can enable recurring appointments for your users.

The availability of the service is defined by employees' working hours, so you would need to edit those in order to achieve this.

When you go to Amelia/Employees, and select that employee, go to the Work Hours tab. In there create several working periods. For example:

My employee would work on "Service 1" and "Service 2" from 08:00 - 10:30, on "Second" service from 10:30 - 15:30, and then again on "Service 1" and "Service 2" from 15:30 - 24:00.

You'd be adding these periods by clicking on the blue + sign next to the name of the day, in the top right.

You can read more about recurring appointments on this link https://wpamelia.com/recurring-appointments/.

Should you have any further inquiries, we kindly request that you open separate tickets for each question and we will gladly help you there.

We wish you all the best.

Have a nice day.
