Swiss Transportation, optional via

Hi there
Could it be possible to implement the optional “via” in the swiss_transportation implementation. It would be usefull to see on whitch side i had to go to the busstation as it is a difference when i like togo to basel ssb. It’s a difference when the bus go’s to Laufen or via Liestal.
Just a small issue.
Thanks in advance.
