I used to use Kurviger and in that app it's crazy simple to modify a scenic route to your liking on the mobile app.
Preferably I would like the same functionality as below (just an example route):

So this is the first scenic route that Kurviger makes from A to B.

I now want to make the route go via the dunes road just north of Noordwijk so I zoom in on the map to that road and tap it. Then Kurviger askes me what type of point I want to add here.

If you use 'shaping point' it just moves the route over that spot but doesn't add a route point. Exactly what I want.

Here you can see the route has been updated to go via that added 'shaping point'.

If you tap on the shaping point again, you can then even modify the route in 2 parts and make it a direct fast route till that point and then scenic from there.

Pretty cool and useful when you can't plan a route in MRA on the PC.

All the above can be tested in the free version of Kurviger by the way if you want to try out what I am trying to explain yourself.
I'm not at all promoting Kurviger, I'm just missing this feature in the Navigation Next app.

Is there an option to do something similar in the app that I haven't found yet?
Or can something like this be added in a future version?
Would be a real big plus for me!

Thanks!
