Anyone have any luck with filament user presets?

Has anyone been adding new entries to the filament settings in the Creality slicer?
I found this feature essential because the PETG printing parameters vary so widely between manufactures. Its much easier than keeping a notebook and tweaking during runtime.

If there are any experts out there I have a few questions:

  1. How do I get the Printer/CFS to recognize the new types? It would be really nice if I could just drop in a spool and select the manufacturer and name from the dropdown on the printer.
  2. What is ‘Pressure advance’ (it is the one item with no description) and why is it not editable?
