Add volume control for radio stations

When listening to radio, the volume is way higher than when listening to podcasts (note that this is not specific to Podcast Addict, the behavior is the same with other radio apps).

This forces me to lower the global sound on my phone as I have no other way to act on the volume, which has the consequences of lowering the sound of every other app.

In my case, it's annoying when driving.

I like to use Android Auto and listen to the radio with PA while driving using Waze. Lowering the sound of my head unit makes Waze’s notifications barely hearable, even when set at max volume in the app.

Could we please have some way to lower the radio stations volume (kind of the opposite of the volume boost feature that exists for podcasts) ?

Thank you
