Feature Request: SoundTransit station style (+ station numbers in the marker)

Suggestion came via email:

Cool site! I have a feature request though 😊 For stations I’d like to be able to specify a line number and station number and have it display, like how SoundTransit labels their stations. Right now I can do the station name, but I can’t nicely do the station line/number combination:

This would probably require some way to automatically generate the numbers for the stations, potentially with some sorting options, and override the autogenerated numbers in case it isn't right. Could get pretty complex pretty quickly, but I do like the look of it, and adding this functionality would also aid in creating other maps like Tokyo or Osaka.
