For longer distances (i.e. where you pass by/through different towns), you can try using the 'Route Via' option. This gives a list of various towns/cities that are in the general direction of your destination. I think you can have up to 3 or 4 different ones (in order, obviously).
For driving within the same city (or wherever really) just take whatever roads you want. The nav system will automatically recalculate your route (and she won't even yell at you).
