Link Specific Products to Shows/Events

For those of us wanting to offer 'Book Your Drink, Meal, Merchandise' etc. with your Ticket, the ability to offer Products, and importantly, cap the amount of Products available per Show/Event, and Report on Products sold per Event/Show would be wonderful.  E.g. 100 Tickets available for a Show, but only 30 seats available for Dinner, or only 50 limited edition merchandise available, or order 10 drinks with your order of 5 tickets.
