Trying to have custom collision on destructible

Hello !
So, I have different destructible meshes for my little game, but there’s a collision problem with some. I have a shelf in one mesh that I want to be destructible, but in this shelf, I want to have some other destructible in it, all using physic. I saw on some old threads that destructible assets can’t have custom collisions like we can do on static meshes, is it still the case ? (I would guess yes).
Does somebody have an idea to avoid that when the game start, the assets become angry and it just explode (meaning they’re all projected everywhere due to their collision overlapping) ? For the beginning, I can uncheck “Start awake” in the physics, but when the player will hit it, it’ll explode anyway.

Thanks in advance !
