I'm working on a personalized sound library that is currently stored on my desktop. Then i had the thought, why don't I put that sound library into logic pro X's sound library so i never have to leave the application?

My question is, how do i manipulate logic Pro X's sound library.
By edit I mean Adding new folders, almost all holding of .Wav files.
I want to be able to pick a choose sounds from the logic pro x library page.

Also a bonus question: If i can edit the logic sound library, what kind of file types can be placed there?

P.S. IM ON A MAC HIGH SIERRA
