Alternative routes to the next waypoint - feature tip

Hi,
(I’m sorry if this topic is raised up before.)
Last week I had a 150 km ride with Kurviger. Between the 2 and 3 waypoints the road turned into unpaved and muddy and I couldn’t follow the planned route anymore, so I decided to turn back and choose another way (in the screenshot: blue line the original routing, red line the new one). The app continously recalculated the route according the original one.
I didn’t find any method to recalculating and following a detour without canceling the navigation.
I would have to exit Navigation mode to enter Plan mode and add some additional waypoints for detour. But it would be much better if I could still be in Navigation mode and there would be a new button beside Gas station e.g. “Detour” and touching this one it can create 3 alternatives of detour (like in Round Trips mode) to the next waypoint, I can select one of them and Navigation can be continue on the detour route.
Is it feasible?
Thx

Something like that is planned for the app.
e.g. to drive around roadworks.
