[Plugin: Google Maps Store Locator for WordPress] Route Between Locations

I’m wondering if it’s possible to extend this plugin to create a route between the locations that you enter. I’m sure it must be possible, but I’m hoping someone can give me some direction as to how to do it. I’m building a non-profit site for a cross-country bicycle ride to benefit American war veterans and it needs to be done within 2 days :/

Any help is MUCH appreciated!
