Archive CC Library

I'd like a simple feature to archive specific libraries that I no longer use. Ideally, documents with links to the archived library should still be linked, or there should be a message when such a doc is opened "This document contains linked files to an archived cc library. Would you like to un-archive the library to relink files?"

I have tons of libraries, many of which I don't generally use, yet I have to scroll through the whole list of them when I'm looking for the library I want. This would be a very helpful organizing feature.
