multiple routes one destination?

[akusokuzan]

I think I maybe confused on the terminology. Also I'm not even sure I'm posting this in the right place. But waze automatically picks the fastest route to my destination and it displays the fastest time for said route. My problem is I don't know which route it is choosing and I don't know how to force it to pick a particular route. I saw something on the site about an input for a substring * to force a route but I'm not sure how that's done. I don't see it here. Am I missing something? Any help would be appreciated.
