Directions with many waypoints

I’d like to get directions from point A to B but with some other waypoints. Problem is that when I get gpx file and import it to some map application(such as OsmAnd) I don’t have this waypoints. Of course created route is using this waypoints but there are not visible as points where driver should stop/collect something or do something.

It’s probably easiest if you import both the returned routing data and your waypoint data into your map application.
