Shipping Methods and Locations

I am trying to set up my store to show different delivery time depending on the location of the customer. The shipping method will be setup for realtime but the delivery time will vary depending on where the customer is located. So I figured I will have to enter different shipping methods for each location that will have that delivery time. I have setup a location with the following postal codes:



A1A*

A1B*

A1C*

A1D*

A1E*

A1F*

A1G*

A1H*

A1N*



The problem is that in shipping methods I can't set the location like I can in taxes. I can only set the localization. How can I get this to work?
