Access to Sub Folders

Theres needs to be an ability to choose what specific folder in a folder you want to randomize. For instance. One producer kits has like 12 different volumes . Adding all those folders will crowd the location area .. There has to be a way OR maybe give us a way to rename folders for Rando. If I got 12 different folders labeled Kicks I’ll add them but I need to know which kick folder it’s from . I don’t know maybe i’m just rambling. But there has to be a way to access sub folders because Category isn’t working it actually zeros out the actual search of what I select.
