Delivery Options

[#1]

Is it possible to add a feature to allow sellers to set delivery areas based on the name of the municipality instead of radius or Canadian postal code? My retail shop offers city-wide delivery. Radius/distance based doesn't work for me because my business is in one corner of my city and setting a radius for say 25km to cover my city means I could also include locations that are 20km outside my city. As for postal codes, my city is fairly large and there would be thousands of postal codes in my city alone. That's not feasible to use.
