Can datepicker be configured so that only certain non-contiguous dates are selectable (and visibly so)? - I need to set up an enquiry form for a resort which has pre-set trip dates throughout the year, occurring roughly every 3-4 days, and allowing booking up to two years out into the future.

It's based on flight dates so if they could choose arrival and departure dates - both from calendars showing only the available flight dates, it would be perfect!
