Categorize presets

I’m saving a lot of presets. They are listed alphabetically. I chose the option to browse the preset folder: on my windows pc they are under user\AppData\Roaming\Dreamtonics\Vocoflex. I created directories there in File Explorer, but when I opened Vocoflex again, the preset list does not show nested directories (I am now in Vocoflex 1.0.2).
How do you categorize presets?
