structure settings Broken by explosives weak metal dmg c - Can I change this?

essentially I finally found the thing that governs how much damage certain damage types do to certain structures, and in particular I want to make Large wild dinos able to damage stone walls.

How would I go about editing this file, as it isnt a new item? Would I go through the same process of copying it over to the mod and editing? I assume I would then have to point everything that refers to it, at it. does that mean I’d have to create modded versions of all stone structure pieces anyway, in order for the modded damage type to refer to them?

Just asking hoping to save myself a lot of time and annoyance…
