Ability to Set Sound Cue Volume Multiplier by Blueprints

The new Audio Mixer engine is amazing and has a lot of super pro features exposed to blueprints. That’s why I find it limiting (and even puzzling) not being able to set Sound Cue Volume Multipliers by Blueprints, especially considering how trivial it must be to implement them in comparison to other much more advanced functions that are already exposed like SubMix switching on-the-fly, or adding/setting effects.
Thanks.

EDIT: It would also be awesome to have the option to switch Sound Classes by Blueprints.
