Using custom filament settings with CFS

Hi!
I am new to the Forum - maybe any of those more experienced guys can help me:

I have a newly bought Creality K2 Pro with a CFS. I would like to use non-creality filaments for a print and managed to create a user preset for the respective filament (some kind of ABS).

However, I do not manage to allocate this user preset to the respective slot of the CFS - I just find Generic and Creality presets in the CFS configuration page. And even if: How can I allocate the respective slot to my model during slicing?

Many thanks

Sven

Does anyone have an idea?
