When already in navigation, and pulling up to see the route options... You should be able to toggle the navigation options, say, in a secondary section below the different routes available.

Examples:
- avoid freeways
- avoid ferries
- avoid toll roads
- etc

That way, you don’t have to go into Th e overall settings of the entire app. The setting stay as default, but the options you toggle are for that specific navigation in progress.

I sometimes want backroads, or whatever. And I don’t want to change the “entire app“ setting. Just that one time. Flexible. I can change those options on the fly.
