I wanted to be able to mass rename stations with a mod
but I could only find a command for doing it created by reddit user MagmaMcFry
this mod is an edit of the "Renamer" mod by GotLag(might currently incompatible with the renamer mod as it uses a lot of the same names for stuff)

all I did was make it so the mod runs that command and replaces each station name that matches the one you are renaming with the new name.
just hover over the station you want to mass rename and press ctrl+R and enter the name you want
