Silent yellow alert

[Cobalt0001]

Hello

I'd love to see the yellow alert mode (when using top priority) have an option to prevent alert noises / not change the audio at all.

I have a few critical things i need to keep an eye on, so i have a few constant yellow alerts, some of the time. But I also just want to listen to the chill music.

One idea is to add an option in audio settings for this. 

Thanks for this awesome game :)
