Selecting Tracks with the same LANGUAGE CODE

[Simon88]

I have an old TV series that is in a set of 30 MKV containers. It contains two Audio & two subtitle tracks with the following descriptions. How do I tell it to always play the 2nd track of BOTH audio & subtitle. I tried Entering "Preferred audio language: Cantonese" & "Preferred subtitle language: Traditional" under Preferences, but it does not work. In my Windows box, using MPC-HC, I simply Enter: 2 under "Default track preference" for both items and check "Allow overriding..." -- that's all... How do I perform this under VLC? Is there another way to tell VLC to play a particular track with the same Language Code?

----
Audio --> Audio Track
国语 – Mandarin - [Chinese]
粤语 – Cantonese - [Chinese]

Subtitle --> Sub Track
簡体中文 – Simplified - [Chinese]
繁体中文 – Traditional - [Chinese]
----
I tried googling all over the net and couldn't find the answer...

Any help is GREATLY appreciated...

Tooltip of "Preferred audio/subtitles language" says: "... two or three letter country code ...".
Otherwise:
Tools > Preferences > Show settings = All > Input/Codecs: Audio track [1], Subtitles track [1] for 2-nd track. Save changes and restart VLC.

Thanks mederi!

Previously, I kept entering [2] for the 2nd track, duh
