How do I save a route so I can use it again later?
On the routing page, select the trip you want to save via the picking, text based, or automated methods. After you have the trip you want to save, click on the "Save route for future use" link about half way down in the left hand column of options. You will then be prompted to provide a "name" for the route and the route will be saved. When you want to use that route again in the future, simply change the "method of routing" to "Loading Saved Trip", click the "Load a saved trip" option (which will give you a list of all the routes you have saved), and then analyze the route.
I had a problem because the "save route for future use" button wasn't available for me. However, the updated resolved this, so if you guys are facing the same problem - update software.
