[Appointments+] Full day bookings without time slot

I'm working on a project at the moment where the client takes full day bookings for mechanical work. They may only require 1.5 hours for a job but they work on it over the course of a day, so they need a car booked in for the whole day. This means there is no need to select a time, and the time options could be done away with altogether. I've been trying to work out if I can achieve this with Appointments+ but so far the best I've got is booking a day with only one time available in the morning. This still requires a customer to select a time, a step that is redundant. Is there any way to set it up to just select a day for the booking without needing to select a time?
