Hello,
I've installed Thronebreaker in french (my native language) through GOG Galaxy. I'd like to play with polish voices while keeping the UI and subtitles in french. Currently, I can select only between english and french in the options.

From what I've seen in other threads, it should be possible but I'm not sure how to: do I have to change the language in Galaxy so that the game downloads the required files? Won't it just replace the original files and settings (I'd like to avoid getting the menus in polish)?

EDIT: I've tried setting Polish in Galaxy options, it downloaded an update and the game is in polish audio + french subtitles as I wanted.
