I've been trying to find a way to make parameterized dadoes for custom products for quite a while. I knew about using hidden products with attached associative tokens, but I'm not very fond of it. It seems like a lot of extra setup, and I feel the need to turn every rib, stud, and stringer into it's own sub assembly in order to keep it organized. I figured out today that the CUTOUT token will do exactly what I want with the prompts I  have already created for the parts on the front end. Jest tell the prompt it's a pocket and your good. Just wanted to share in case anyone now or in the future is banging their head on that same wall.
