Unique File Names Per Folder?

I'm pretty sure that this is not possible but I wanted tocheck anyway.

Our vault is organized by project and within each project are twofolders (CAD and DHF). I would like to enforce unique file names inthe DHF folder, and allow duplicate file names in the CAD folder,unless it exists in the DHF folder.

The CAD folder is for concept work and it would be a pain to useunique names, but I recognize the importance for approved files(DHF).

Any thoughts or suggestions?
