Sort brushes into groups?

I downloaded the 'kyles brushes' pack but having to a) wait for them to load to be able to select them and b) scrolling through the near 450 brushes every time is rather tedious. 

is there a way to group brushes together? 

if not I think the brushes should be available to download in separate packs. Eg. group all the ones labeled 'kyles drawing box....' or 'kyles ultimate oils...' together. If this is already a thing pls direct me to it 👍
