Problems with Sound Groups

This week I tried to make volume sliders to adjust the sound quality and in doing so I realized some problems with the Unreal Engine's default sound options. One of the problems being their new Volume Slider widget that is still currently experimental, you can read the issues we faced with that here. My biggest problem that I found was in the default audio groups/classes Unreal has, they have a few different categories, Master, Music, SFX, Ambience, but what it doesn't have is functionality for the master class to alter the volume of the other groups, as you can see their is no connection to those other groups in the Master sound class:

The solution I found to this problem was making my own Master sound class that is connected to my own Music and SFX classes so when the Master class changes it also adjusts the volume for the music and sfx. The problem with this approach was that I now had to go through every single sound file that I set to be connected to the default unreal sound classes and had to reassign them to my new classes that was very time consuming because we have a lot of music and sound effects. But hey, now the sliders work!
