APPOINTMENTS + settings bookings

hi for a salon I want to use the APPOINTMENTS + plugin so that clients can book their appointments online. the problem is that some treatments have an interval. For example, its color lasts 45 minutes, the color must dry for 30 minutes and then there will be a 30 minute treatment.
it is possible that a customer books a treatment for color and that the plugin automatically book an appointment with a half-hour gap where another customer can make a booking?
Thanks for your help
