Scaling the volume of music in a soundscape with the slider from the settings

[funky fred]

I've seen that it's possible to have custom music in your map be able to have its volume scaled with the volume of music in the settings and I've played multiple maps that can do this, but when I try to find something on how this is done I get absolutely nowhere

Anybody know how this can be done?
