Preselect a service for calendar on Appointments+ Marketpress Integration

I am setting up A+ and MarketPress to allow party bookings and additional services. A "product" page is a booking for a particular type of party. Is it possible to pre-select the service so that only the calendar for the particular party type is shown on that party product page? (ie so the customer doesn't have to select the service from the dropdown) eg see here http://goo.gl/NbECH
