Heya,

I'm trying to go through Europe in Co-Maps. Particularly, I want to use offline maps to avoid aggressive roaming fees during one part of my route, as well as have a robust backup if online maps breaks. This seems to work great in preparation so far.

One thing I'd like to account for, is that driving through Switzerland is very expensive. I would rather want to detour slithly south through Austria, but I can't find a good way to communicate that to the app. I could try with some intermediary stops, but that seems like it would muddy the routing algorithm even more.

Is there a way to prefer/avoid areas or countries? Or a way to prepare a fitting route externally in advance, then reliably have it work in the app?

Thanks in advance.

Under routing options in the settings there is a setting to avoid tolls. I have not traveled through Switzerland or Austria so I do not know if the roads you mention are tagged to work with that feature or not but you could test with a local road you know has tolls and then look at the roads you want to avoid in Switzerland on https://www.openstreetmap.org/ and see if they are tagged the same. I took a look and here is an example from the A12 near Bern: https://www.openstreetmap.org/way/4873847#map=14%2F46.94593%2F7.42161 It is marked as toll: yes which is the same as roads I know to have tolls that the feature avoids. Again, test for yourself but it looks like this might do it.
