Limiting the number of option on the Appointment + Bokign for

Hi - this is a two part question. I'm using the Appointment + plugin for to allow for booking of two time slots per day. (11am- 1pm) (1pm-3pm).

Part one - My questions is how do I allow for two bookings per day? so 2x (11-1pm) booking and 2x ( 1pm - 3pm).

The second part is that we have a pony party available, but this piny cannot be in two places at once, so There is only 1 pony party available in the morning and one in the afternoon. How would I go about implementing this please?
