Multiple quantities for a product
 

I am developing a tour (bus tours) site and I want the user to be able to choose what kind of tickets he wants. The product options are "Adult - Standard Class", "Child - Standard Class", "Adult - First Class", and "Child - First Class". Now I want the user to be able to enter what quantity he wants of each kind of ticket. http://www.insearchnow.com/order_page.jpg
but if I enter for example 4 in the "Adult - First Class" field and 3 in the "Child - First Class" field and then click on "Add to cart", then it only shows 3 times "Child - First Class" tickets.
Is there a way for multiple quantities for a product with different product option?

Multiple add to cart process.

Interesting request although the original poster is probably not able to access this anymore.
