Feature Request: Assign Train Stations by Substring

[GoatsWithPants]

TL;DR:

Allow us to assign train stops based on a substring (or multiple substrings) as an alternative to the full stop name (ex, instead of assigning a train to "iron provider," use ANY station with "Iron" and "provider" in its name)

Why?

To do multi-item stops with the current system, to must have a train schedule with every stop listed which becomes extremely long. With substring assignments, you could have one schedule entry per item, and supply ALL stations which require that item.

What?

Add an option to assign a train to a "substring name" instead of a "full station" name. Currently, you can have many stations with the same name, and a train will service all of these. I would like this exact functionality to be extended to "any station with #substring in its name", so that mutli-item requesters and providers are easier to make. You could make a station named "iron + copper + steel provider", and use substring assignments to access this station without having to explicitly list every mutli-station by name.
