UV map and scaling

[TenthArchitect]

Would it be possible to add a toggle to lock the UV coordinates of a given block or all blocks so one can scale the object without the UV coordinates changing?

Or any other way preventing the UV coordinates from changing when scaling, I am trying to do a couple hundred shapes that use the same UV map but are different sizes and the only work around I've found is to scale the model and copy paste the UV coordinates from the pre-scaled back up I kept. Each rescaling takes about twenty minutes of copy pasting and I feel like there has to be a faster way.
