Simple way to avoid highways?

I have a Drivesmart 65 and there are times I will take a trip where I would like to take highways for most of the trip. I will set the destination with "Avoid Highways" unchecked and start my trip. Once I near my destination rather than have the Garmin take me out my way just to get to a highway I dive into the menus to check the "Avoid Highways" so the last few miles are shorter without the Garmin seeking a highway. Rather than go into the menus to uncheck the "Avoid Highways" box. Is there a shortcut to do this? Like a voice command or setting up a custom icon to check/uncheck the "Avoid Highway" box?
