I don't think MRA can simulate exactly what your after.
Calimoto is probably your best bet for that.
However why not try out creating your own route directly in MyRoute-App.
Anyways ,the info below outlines what the MRA Scenic Route Generator can do.
You can generate Routes based on Time or Length.
You can then decide how Curvey you want the Route
You can then set the Height of the Route
You are then given 3 different Route options.
You also have the option of setting the length of the Route.
You also get the Curvey and Height options and also you can dictate the direction based on North, East, South and West as shown below.
