Is there a quicker way to Auto-Populate genre playlists?

[TheShedHead]

Hey guys, I'm new here.  I was starting to manually add playlists for genres, when I realized that the theme I'm currently using (Unified), already has all the images I need in the Theme folder. There are about 50 different Genres/Categories. Do I have to manually add one at a time, name it correctly, and auto-populate the playlist based on genre?    Is there a faster or better way? 

Thanks in advance!

Thanks!  Is there a way to auto-generate child playlists for my whole library? I only see that option for individual Platforms, and not for "All Games".
