Yes! In the 'All Deliveries' tab in the Deliveries Tab, then claim all the items you're going to pick up that day. In 'My Deliveries' tab, tap the first item, then tap details, then tap 'Open in Map.' This will open the Google Maps app with your route in it!
PLEASE NOTE: You MUST have the Google Maps app downloaded for this feature to work properly. The mobile browser version of Google Maps will not be as functional.
