If I understand your request, you need to have a many to one relationship of stations to an order. Not always, but some times you need to select multiple stations and see the related city of license within an order.
What I would do is create an order_stationlink table that you would add station(s) to an order and their license would be displayed when the station is selected. From the order table, I would create a portal of the link table with related fields back to stations to show all station information for an order.
Good suggestion. And I'll use the List function to get the portal data for stations throughout the rest of the system.
