I can't think of any way that's sensible. Sure, you could build a suitelet that displays CSV files from the FileCabinet, but unless you're using internalIds to identify files, or absolute paths or something (which would be horribly user-unfriendly), it's actually a pretty challenging coding problem. You want the point-and-clickiness of the File Cabinet, but there is no User Event Deployment Type for File, so you can't easily add a button with built in NS forms. I think you're SOL unless you want to build an entire UI that's better than the File Cabinet.

You could have a suitelet with a field that you populate with select options after doing a search for files (in a given folder, for example). The user selects one of the files and hits submit and then the data is displayed using NS form in a pop up? Maybe? Still, it would be an entirely custom interface, not the File Cabinet.
