How do I save sound settings?

Hello! I’m trying to make a master volume slider for my game’s settings menu, however, I am unsure of how I can save it along with all my other settings without saving it within my Save Game itself. I want to save it as a setting instead, as shown in the nodes below. Is there a way I can do this or do I have to save it within my save game object? I hope this makes sense - thank you!!

I think you have to do it in the save game. Most things will go there. It’s only some ini file settings that are saved by game user settings.

I see, thank you =)
