First of all, thanks for this mod, its exactly what's needed to take advantage of 2.0 train coloring facilities!
However, the mod works only for half of my stations --- I only use [item=...] tags for my unloading stations, but all my loading stations are named the same (while a full train needs to get routed to a correct station, an empty train can pick arbitrary free loading station).
I can color these stations by first renaming them to include the tag, coloring, and renaming back, but that's very cumbersome. It would be very cool if the mod suggested to pick an item if the station selected doesn't have the item tag
