My solution attached.

Was able to build a fully dynamic solution (meaning the input data could change and nothing else needs to change to get the correct result) WITHOUT the use of a macro and fairly simple design and not overly complicated.

My thirty-sixth workflow! I could finally get the same output. Macros, you confuse me so much...

This took me a while, but it helped me understand batch macros better.  I got it right, but slightly different than the example.

Originally while making this, I had figured out the rough solution. The only issue was that I didn't exclude the right items, something that took a while to be fixed.
