Adding sound when a destructible FBX chunk collides with an object?

I’m trying to add a sound when there is a collision with the FBX chunks. I can add the sound to the initial impact, but I don’t see any way I could add sound to the chunks.

Once I’ve added the sound to the chunks, I’d like to devide them into 3 catagories: small, medium and large and then give each of these catagories a relevant sound cue. This will make the large chunks sound like boulders colliding, medium like bricks and small like pebbles/rocks.

How could I do this with blueprints?
