Custom Music / SFX Production Audio Library in FCPX 10.3

I was wondering if anyone has figured out how to get custom production audio libraries back into FCPX 10.3? Before you could just drag the folder into the music folder and then they were listed and searchable. Now, after updating to 10.3, all my music and sfx production libraries are gone and only the Apple version is available in the Audio Content...

I love everything 10.3, but I don't like how Apple forces iTunes / Photos for file management. This needs to be resolved so using custom libraries on NAS drives or shares can be added to FCPX without having to go thru them as it use to.
