link files to a client (as you currently can for a project)

The ability to link files to a client (not just a specific project) would be invaluable. I can think of countless instances when having specific files linked to a client, for instance a preferred version of their logo or a Creative Specification Guide or perhaps a template (i.e.: Indesign) that would apply to more than one project for the client and doesn't go away when the project is done.
