Train operator changed ➡️ looks ugly

[nixmeer]

Hello :)

since January 1st, line "S3" of the "S-Bahn Rhein-Ruhr" is no longer being operated by the Deutsche Bahn but by Abellio which is a private train operator. It's still the same line "S3" but different trains and the DB API names them "ABR S3" (not only my mirror uses this name but also all smartphone apps I use).

This looks just ugly... is there any way to not just change the background color, border-radius etc. but also the displayed name?

Best

Jan
