Stopping Destructible mesh from fracturing all the way

Hi all,
I am trying to create a destructible mesh that the player can chip way at. I also want this mesh to have a transparent material on it similar to glass. I have made the destructible mesh just fine, the only problem is when I shoot it anywhere I instantly see all the fracture lines. Is there a way to only have the fracture lines show up that are near the impact or not show the fracture lines at all and just have the pieces break away.

Mesh Before

Mesh After One Shot Anywhere

On a side note I would also like to have a column that only has the outside break away and keeps a centre support structure if anyone knows how to do that.

Thank you,
