Mute sound for specific notifications

[notDavid]

Hi there,

if i see correctly, it's not currently possible to mute the sound for specific notifications?
If so, please consider adding the ability to do this.

Currently i've created an empty sound file, put it in ~/Library/Sounds/silent.m4r (macOS) and then use NOTI_NSUSER_SOUNDNAME="silent" noti, but that's kind of an ugly workaround of course...

Something like NOTI_NSUSER_SOUND_MUTE would be useful.

Thank you!
