Custom Audio Volume Shapes

I am not sure about anyone else but for our game we are building we are currently having to use multiple audio volumes of the same track to fill an area but exclude it from a building however due to the complex shapes of the building it isn’t as simple as just a couple of cubes as the buildings have complex anges moving on x, y, and z causing many issues for us including audio tracks initially triggering correctly and then messing up later on due to it being multiple different spots and then we have the issue of dead spots caused by being unable to fill the space efficiently. All I am asking for is the ability to creat a mesh that the audio volume will conform to.
