there are three "favourite" categories which were intended to be used as custom categories. those are not being used by the patches in the rom section. unfortunately naming you own categories will not be possible due to internal restrictions.

Well what I did is
I created abbreviations for patches like: ST-strings, PD-pads, PL-plucks etc. So patch name inside bank looks like PD-Andromeda. Then I use function sort alphabetically to place patches in order
ST,LD,PL, etc. That helps navigating inside bank, for banks environment navigation CATEGORIES are useful. So this trick means I need to listen to every patch in a bank, rename it and place CATEGORY tag. That makes sense for fast workflow finding source sound to tweak it then. All is IMHO.
