PDF Portfolio "Add Folder..." No Longer Retains Folder/File Structure

In older releases of Acrobat Pro, PDF Portfolios allowed you to add Folders and it would retain the Folder structure (including any sub-folders with the Files inside of those). On the latest version, it goes through the folder and any sub-folders and only imports the FILES that are in the folders (and does not include the folder structure those files reside in). How can I import a Folder and maintain the Folder's internal structure?

Just to be clear, I want the PDF Portfolio to match the Folder structure on my computer like:

• Parent Folder
  • Child Folder 1
    • File A
    • File B
  • Child Folder 2
    • File C
    • File D

And currently when I Add Folder -> "Parent Folder", PDF Portfolio only imports:

• File A
• File B
• File C
• File D

Please help solve this basic functionality issue. This is the entire reason Portfolio exists rather simple Attachments on a PDF!
