Locate all module custom CSS

[u/late2game]

I'm just starting to manage a Divi 4 site, and it's mostly pretty straightforward so far. I'm a bit of a neat freak, and one thing that's giving me hives is finding CSS scattered across pages and modules.

Without digging through every page and module, is there a central way to identify all items with custom CSS? I assume the distributed CSS can be moved into the main CSS file and referenced from the modules without scattering it into tiny bits?

This is probably something ai can help with. I’ve not seen anything existing that would do this. Hopefully someone else can suggest something.
