How to add my FontBook Fonts as a Collection

Hello, I’m a new subscriber using a Mac Mini and Sonora OS.
I have about 1030 font families in my Apple App, FontBook.

May I link the fonts in Fontbook to access them within the app?
If so, can you point me to instructions?

P.S. I did try to link the app Fontbook by “adding a new collection” but I ended up getting the system folders. I backed out and deleted the link.

Thanks, M Mead

Hmmmm. Does no one know the answer? Thanks.
