Describe the feature

So the user would take a screwdriver and smack the face of a framed block, which would make any face that is smacked the secondary material on that framed block. It would only work on single material framed blocks because i would imagine having to program in the toggling on the double material ones would be ludicrous and unreasonable.

Plus, this way it would only add 2 nbt tags (in theory), it would add a ToggledFaces list, and of course, it would have a second camo tag like the two-material framed blocks. I'm sure there's better ways to do it, but I think it would be pretty cool, and it would make train roofs way slicker.

I'm not sure this is particularly useful considering you can achieve the same effect with clever usage of existing two-material blocks. If there are two-material blocks missing for certain cases, then I would rather add those (assuming they aren't too niche) instead of adding another layer of complexity to the camo application system

Closing as this provides fairly little benefit at a significant cost of complexity both for the user and in the implementation.
