Could we please have multiple mutually exclusive filter sets and select which one to apply on a per-request basis?

My scenario is as follows: I have a player that is capable of playing tvh channels, but it will ignore all but the first substream of any kind. (i.e. a channel with 3 different audio streams - Stereo, 5.1, Audio Description - would always only play the audio from the Stereo stream with no chance to switch to the 5.1 or AD stream. This is especially bad when the AD stream is in the first position)
Now I can set up an audio stream filter to choose only one audio stream, but I have to apply that very same rule to all channels in the same way.
If there's a channel with multiple language streams for example, I'd have to choose one language upfront and am unable to change on the fly.

What I'm requesting is to have multiple (named) filter sets and choose which one to use during playback similarly to how you can already choose ths stream profile right now.
