Ignore the tracks that you won't use.

[xZabuzax]

Please add an option or an easy way to configure this script to ignore the tracks that you won't use, for example, if a video has over 10 audio and subtitles, I want to cycle through the ones I will use and ignore the other ones because I won't be using tracks like: German, French, etc... I'm only interested in Japanese, English and Spanish.

In short, if a video has 10 tracks, I want to configure this script to only cycle through 3 and ignore the other 7.
