How to make a custom design library?

I want to use the built-in design library to quickly find parts that I frequently use.

I can add a folder or save parts in the library but they are seperate than the actual files that I use.

For example, I want to reference several parts from several different folders (rivets, nuts, and pems for example) in the same library folder (Misc. Parts)

I would have to save them all in the same folder for it to work. How would I go about just referencing the actual files?

Also, can I name the shortcuts (like 8-32 screw, .5" instead of 43-135 filename)?

Thank you in advance to any answers!
