Fixing FAB plugin materials without modifying the originals

FAB plugin contains various master materials which are used by dependent assets you can download. Unfortunately, those materials don’t contain certain important flags like using with nanite or voxels. One solution is to modify them directly in the plugin, but that means altering the plugin for every developer after every update. An alternative is making a copy and manually updating child materials, but that’s a lot of error-prone work. Is there a way to make a permanent fix?
