How to force "Least Use of Highway" on A Garmin Nuvi (GPS Magazine)

Hope this helps. Sometimes it takes awhile to find options and anti-options.
So..I have a NEW Garmin Nuvi 750. Yesterday I needed to go to O'Hare Airport in Chicago from Hammond, Ind. I always take 294 up to avoid going thru the city (Chicago). The Garmin set the route going up the Dan Ryan thru the city, of course, it recalculated when I didn't but kept directing me to go into the city whenever it could. It continued to recaluculate each time I didn't take the exit it indicated and just went to the next one. Is there a way to set a route using a specific road?
