Wildcard Postal Codes in Canada

I’m hoping you can help me out. I’m trying to use your plugin to set-up a local delivery area in Canada. The way our Postal Codes work are a series of 6 numbers and letters. For example: M6G 1S9 is a postal code for two to three houses. However, I need to target all houses in M6G (and M6S, M5T etc.). Is there a way to Wildcard postal codes?

Also I need to set it up so deliveries are free if the customer orders over $50. Hopefully I’m explaining this properly.

Thanks!
