It would be very nice if it were possible to turn on or off "no-stop zones" not only on individual tracks, but also on an area.

With operational train networks, no-stop zones are almost completely unnecessary, and can even sometimes lead to stuck one train or traffic jams. Switching off "zones" on individual tracks, especially when the entire map has four track railways, is very time-consuming and frustrating.

I feel you. No-stop area select would be so convenient on my layout- I've got a few no-stop zones in key areas where they're needed to prevent backups or enforce route priority, but something like 95% of the default no-stops get removed because all they do is slow things down.
