How to change Animation bound Audio Volume in Blueprints?


How can I change the audio Volume in the image in Blueprints? I have an Options Menu in which the player can change diverse Audio like Music, SFX and so. Works fine for the rest of the Audio I have in the Game to set the Volume Multiplier from a Slider Value from the Options. The problem is all sound which are bind to an animation are not influenced by this Variable how can I get acess to this? or what do I have to do to do so?
