How do I restore an accidentally deleted subfolder from a Promotions dossier?

To recreate a subfolder, upload a document using the promotions candidate submission webform.
https://documents.med.utoronto.ca/forms/candidatesubmission
Select the Document Category for the subfolder needed, then attach a file and click "Submit".
The subfolder will be created in the Dossier folder within the promotions candidate folder.
