Make sure any apps you want to run on SYNC are already running on the phone. If they aren't running on the phone, they won't show up on screen.

Yeah then the "detour" function is probably more similar to what you're looking for, but that's only an additional route on top of the fastest/shortest/eco routes. Another thing you could do is set the route, start driving the one you want with the prompts muted, then unmute them once it updates the route to the one you wanted.

Go into the Navigation settings and disable the option to automatically select the fastest route. You'll get 3 route options when you set a route then. http://www.fordservicecontent.com/Ford_Content/Catalog/owner_information/Ford-SYNC-3-Supplement-version-1_sycsy_EN-US_05_2015.pdf See page 84.
