I believe you can do that with Fences. Just need to create shortcut to those documents. You can rename shortcuts into something else even the original file is the same name with the other document in another folder. Move the shortcuts into your desktop area. Locate and move those shortcut info a Fence. Pin that Fence in Start11. With that your original documents still in their respected folders. Just the shortcut to it is in that Fence.
