Smooth SandStone should be "craftable" using Cut Sandstone

Cut Sandstone its like a cleaner version of the Sandstone right? But you can only use a Sandstone block to make a Smooth Sandstone, i think the possibilty to smelt Cut Sandsotne to turn it in to Smooth Sandstone should be really intresting, or another idea the Stonecutter can cut those little cracks that are in the Sandstone block in a Cut Sandstone to make it Sandstone again
