Can I allow multiple people on same paid booking? Specified appointment start times?

We love the appointment plus plugin as we are building a fishing charter website.

1. Can we allow a paid booking to include more than 1 person? ie set number of people to ‘2’, that then decrements the capacity by 2?

2. Can we set specific start times for an appointment ie customer can only select 7.30am or 12:30pm for a 4 hour appointment? (currently customer can choose a 4 hour slot starting at say 11am.)
