Hi Whitehawk,
You would do this by making a Material Instance of the Material you are applying with the UV coordinates converted to a parameter that you can adjust. (Material Instances take way less time to compile than the original material.)
Here’s an example of what I mean: (The rectangle mesh on the left is a duplicate of the mesh on the right scaled in half with a material instance of the wood applied with the “U” set to be .25 from .5)
