Cylinder Stylus Qualification

Greetings new Zeiss forum.  I apologize for the potential reposting of this, however I am still dealing with creating an internal tool to help dial in the accuracy of my stylus setup.  First, let me describe the application.

The ask is that we measure the OD on an a sealing surface of a port, meaning the feature is a torus (in CAD) and I need the maximum material condition diameter (largest OD of the donut).  The torus R2 is VERY small so characterizing this feature with small arcs is not possible, nor cost effective.  So the plan was to do a diametrical sweep around the circumference using a cylinder stylus, since a sphere maximum condition riding along the torus maximum material condition would result in variations that are not representative of the feature.  Picture two spheres staying perfectly aligned on their respective apex during the sweep.

My question is this, I know that you can qualify a cylinder stylus through the software, but it doesn't work.  The "Creating Disc Probe" instruction that was created by Mr. Oakes was very helpful since I just adjusted my disc height (it's technically a cylinder).  Why can't this be fixed in the software?  It's just a matter of automating the complex trig, same thing it does for spherical styli.  I've attached both the "CDP" instruction and my working through this using sections from the CALPYSO manual.

What have people done to make their cylinder stylus qualifiable on a regular basis without having to have a external Excel sheet to keep changing their values?  Or is this what I'm stuck doing?
