Re: Dynamically change trainstop names richtext icons with circuit signals

... once the circuit signal changes, there isn't a clean game record of the stations original name, I'd happily take a set first/last icon option as well. It'd constrain engineers in how they name their dynamic train stations, but probably worth the compromise for those of us inclined to go this path.
