Limiting which parts in a directory show up in a design library

I have a directory which has 1000 parts in it, and I want to create DESIGN LIBRARY location which only has select parts in it and does not show the entire directory,. Is there a way to do this? I cannot create a separate location with just the desired parts in it or even copies since this is the user maintained database.

I just want specific parts to show, not the whole directory..

Thanks !
