How can I make a material function that utilises CLOTH nodes?

[Crofty]

I can’t see any “fuzz” or “cloth” nodes on “make material attributes”.
If I wanted to make a range of cloth materials into single functions, how can I store that fuzz and cloth information in the function itself?

I could insert another output but then I wouldn’t be able to use material attributes.

Here’s an image to better describe. The clearcoat shading model seems to have nodes in the material attributes. But nothing for cloth.

I have the exact same issue. No fuzz or cloth in the makematerial attributes
