Repairing camp items before they're completely destroyed [Prefab]

Is there ANY possible way to repair camp items instead of waiting for them to finally get destroyed. I have a prefab that is about 75% destroyed from just random enemies showing up. And it just looks awful I never new how much of an impact and that it had different stages of being destroyed I mean there's a huge hole in the wall. Anyways is there a way to fix it now instead of waiting for the inevitable?
