AudioVolume Exterior LPF based on Sound Class

Is it possible to only affect the Exterior LPF of certain Sound Classes from within an AudioVolume box? I have some ambient sounds coming from a room and I have specified different Exterior LPF levels for several different AudioVolume boxes in a hallway. I’ve set a new Sound Class called “Distant_Screams” of which the audio files point to. However, the Exterior LPF is also affecting the room ambience which is set to a Sound Class of Ambience. This is resulting in a very noticeable low pass filter on the room ambience.

Maybe there’s a better way of achieving what I want?
