Support "remove all but" for Remove audio/subtitle streams by language

[Roboroads]

What is your feature request?

Now, within Remove audio/subtitle streams by language you select which ones to remove, but I would like to select the ones to keep and remove the rest.

I am looking for this also, and the option to keep native language. I find it difficult having to add so many languages when it would be much easier to have "keep native" (as I have a few foreign shows where I cannot stand listening to dubbed audio!) while keeping english subtitles
