Alternative Routing / Choice of Routes

Sometimes users can face obstacles following a specific route: there may be stairs and the user is handicapped, a gate is closed at certain times, …

It would be great, if the author of a tour could give the user a choice between alternative paths, when such obstacles are already known to the author. The interaction by the user could be minimal, but of course it would require taking out their phone. Unless the could respond to a question asked in the audio via their microphone, but that is probably too much of a hassle and might not always work.

This feature could also facilitate optional content such as “do you want to take a short detour to see xxx?” or “would you like to learn more about yyy?”.
