I would love to have a way to scan only a subset of a larger rail network for rail signal planning placement.
I have a small megabase starting up, and every time I scan, it freezes the game for some seconds.
Instead of scanning the whole rail network, I'd rather only have it scan the area I marked with the mouse when dragging.
Could this be added?
As it stands now, it becomes increasingly cumbersome to use as the rail network grows in size.
