Can I quickly switch mono/stereo and left/right audio balance?

I want to be able to quickly toggle my iPhone audio settings, between "mono, right channel only", and "stereo, both channels". I can do this with a whole bunch of steps by going through Settings / Accessibility, but is there a faster way? Is there a magic phrase that Siri will understand that can help?

Explanation: my left ear is both near-deaf and over-sensitive (I know, it doesn't make sense to me either), so when I'm listening to headphones, I like to have mono audio, right channel only, nothing on the left channel. But when I'm listening through speakers I prefer stereo, with channels balanced. Since I'm going back and forth between headphones and external speakers many times over a day, I'd like to do this more efficiently.

Thanks for any suggestions!
