For me designing road layouts in Civ 5 was really fun and I miss that. I don't like how sometimes trade routes will go all over the place in Civ 6, making a mess of the road network. Sometimes they look really bad and don't make sense. I'd like to be able to choose which tiles a trader goes over to make roads.
I could picture on the trade route selection page, being able to click the tiles you want to use, or clicking arrows along the route to change the used tiles. Then with future routes they could prioritize the use of existing roads. As long as you use the same amount of tiles as the auto generated route I think it would be fine.
