Able to set different audio for different channels

[Endgame]

Now I can set different audio setting for different channels which was not available earlier.
e.g. Hindi audio for Travel XP HD, English for Discovery HD.
But earlier if I changed​ audio to Hindi for Travel XP HD, all channels having Hindi+English audio would changed to Hindi audio automatically.
Same applicable for DD & Stereo Audio.
Not sure from when it was possible.
