Add email notification support to virtual directories in User Manager

Please consider adding the ability to set up email notifications on every file upload when setting up virtual directories to avoid having to create custom rules in Event Manager.

Justification: This would be particularly to us as we work with the acquisitions that aren’t on our tech systems yet and people who share and look for data in the shared folders have to check for changes daily rather than getting notified. Adding the ability to set this up in User Manager makes our workflow much simpler.
