How can I modify the time dilation for breakable objects?

I am trying to slow down the game at certain points during gameplay. I can use “set custom time dilation” to change the speed of characters, objects, and particle effects belonging to a blueprint, but I can’t figure out how to slow down the chunks from a destructible.

I want the destructible to behave like it does if I change the global time dilation, but I don’t want to change the global time dilation. I want to only change the elements that need to be slowed.

Did you ever manage to figure this out?
