patterned "remove"

Project https://cad.onshape.com/documents/bb62ee15a8f72336ba6a5609/w/87910df456753a607749e92d/e/3f3ac5948b1b2d8bcbf7619a?renderMode=0&uiState=68a8231d9ee4dc37cc479e46
Here is the problem: I have three parameters: #segment_thickness, #gap_size, and #segments. I want to be able to change any of these three and get a properly-semgneted worm body with no extra effort. There is the picture of what I do it I do an extrustion and replicate that extrusion according to my three parameters.
But what I want is that instead of being New extrusions, they are Remove extrusions. If I change any of the three parameters, the "correct" behavior occurs. Everything resizes as I want it to.
Why can't I pattern a Remove extrusion? How do I set this up so that no matter what parameters I change, everything is correct? The important parameter is the #segments.
I had asked a similar question and received a working answer that was, to me, incomprehensible. I have done a completely new design and gotten this far, but now I'm stuck again.
It should be legitimate to replicate in a linear or circular pattern any extrusion, including Remove. Key here is that I should only have to edit one parameter value and everything works out correctly, with no other modifications to the sketches

Hey @joseph_newcomer,
Have a look at this tip:
https://www.onshape.com/en/resource-center/tech-tips/tech-tip-how-to-use-variables-in-patterns-to-vary-features
This should work with "add" and "remove" features. There is also an example here where it creates new bodies:
