How to add new Asset type Categories to EAssetTypeCategories?

As the Title says…

I know that EAssetTypeCategories is including an enum with the basic Types… But i also know, that f.e. Paper2D adds his own Category when the Plugin is enabled… soo…:

Is it possible to create a custom Category for my additional created Asset Types?
If yes, how?

There’s a limit; I think it’s 16 categories if I remember right.

Btw, I remember I had to ASK Epic to include my own asset category for plugin packs sold on Marketplace because said limit.
I think this is why they don’t want everyone doing it, the space for that is way too limited so they don’t share any public examples.
