Not really, the basic problem is still true. The UI would significantly more complicated and this would require huge changes.
The question is, does this problem justifies that the UI gets more complicated? My opinion is, that it is not. Especially as this would influence the basic function of planning a route. If we would be talking about an advanced feature, this might be different.
It’s OK if only power users use some of the advanced features. The basic features should be usable as easy as possible without requiring special training
