The ability to change audio/subtitle track for an entire show manually

[Lonli-Lokli]

So I would like to have an ability to set audio or sub for a show manually
I know there is a preferred language in the settings, but there are situations when you would like to have some shows in another language, other than your account.

Eg if I want to learn some language I would like to open the show, set up language to the specific one (Chinese, Korean, etc) and listen it every time, without needing to manually switch each episode

Same goes with subtitles

You can already do that.
Just edit the show at its highest level, then switch to the Advanced tab and scroll down to the bottom.
