Multi languages for audio

[nothingness]

Hi, I usually watch videos in English and Japanese. Some videos provide multi-languages such as Hindi and Spanish. I prefer listen to them in English or Japanese.
Adding a preferred language in Preference - Audio - Tracks - Preferred language is simple. However, how do I add multiple language? I mean English and Japanese?
I typed Japanese, jpn, English, eng, but it didn't work.

Tools -> Preferences -> Show settings: ALL -> Input codecs
The language fields are on the right panel
For instance for English language first and fall back to Japanese language, type in "en,eng,ja,jpn" (without quotes and without spaces) in the audio and/or subtitle language field
Save the preferences then exit and restart VLC for the change to take effect.

It works! Thank you!
