Order Import with Duplicate Customers

We're looking at running an order import and curious about what happens when a customer has more than one set of contiguous seats. Anyone know off-hand if we will end up with a new order for every row in our import file, or will the utility put all seats for a given customer in a single order? 

We'd prefer to end up with different orders in the case when we have more than one row for a given customer. Anyone know if that's the default behavior?
