Remove System Fonts from Font List

Having system "fonts" like this https://prnt.sc/rcCOaZDLJERe load a font list is a huge memory hog and time waster. Now I have to scroll through hundreds of useless fonts that Mac OSX will not allow me to remove, but for some reason Adobe CC imports into the list. Why is there not a filter or preference to only pull fonts from the User level, not system. This is ridiculous and is making the apps useless and cumberson. PLEASE do something about this.
