At the moment a free slot gets marked with

<a href="#" class="time-value" data-val="12:55">12:55</a>

and a full time slot

<a class="time-disabled">13:00</a>

But if a time slot has multiple slots the calendar doesn´t show how many are already given.

Maybe there is a way to give the class attribute the number of already occupied slots?
e.g. if there are 3 slots for a time slot and one is reserved 2 are free add this number to the class attribute

<a href="#" class="time-value 2" data-val="12:55">12:55</a>

This way the calendar could be styled easily to show that one or two slots are occupied Thx !  Btw   great plugin and great work done
