I was just wondering if theres a way to do a map correction from the route review? Im wondering because right now theres a huge rockslide between exit 20 in NC and exit 451 in TN on Interstate 40. I go that way a couple of times a month. I was planning a trip through that area and my TT keeps wanting me to go I40 which is impossible. I used the avoid part of route option last time but would love to have it just go the alternate route. Is this a possiblity ?
