category markup

Using WP 5.6 with an underscore theme, I have the Gutenberg plugin 9.7.1 in place.

I like the plugin but how do you create the category for the pattern you create with it? The template I created comes up when I choose the uncategorised. However, if I want to create a greate many patterns for different uses, it would be quite inefficient to apply them, e.g. scrolling through a great number of uncategorised patterns each time.

Thanks for your help through this plugin. I hope it can be improved and eventually incorporated into WP itself.
