Does this only swap the single section of track you click on ... or does it swap out the tracks globally all over the route ?
It would be nice if it swaped out an unknown missing kuid track, and globally replaced it with the track of your choice
I am still used to 04, 06 VistaMare Trainzmap where all instances of the track is replaced (only works in 04, 06)
And I usually place 2 track spline points, delete the track in between, place in a short section of the desired track, then delete the track spline points in the intended direction of traffic flow
