Garmin Road Trip - can you change routing options on the road?
 

I'm playing with Garmin Road Trip (mac) and creating a 'route' down to Budapest and back. I know that when I'm actually on the road whilst my waypoints wont change too much over 7 days I will quite probably change my mind on routes.

So my question (as a new Garmin user) is can I change a route created in Road Trip when I'm on the road - more specifically can I change the routing options 'avoid toll roads' kind of thing? Is there a way to set this in Road Trip?

PS - I'm using the Garmin 660
