Bundling USA maps would be nice

Just discovered this app. As a truck driver, I love the option of telling the app Im either driving my car or my truck. I downloaded the USA version of the app and then purchased the maps for Canada which let me download all provinces and territories at once. Unfortunately, I cant do that for the USA which really annoys me since Ill have to download every single continental state one by one. How about a "Select all" button to make things easier on the users ?
