If I have 2 top-level folders, Events and Email Blasts, I should be able to create subfolders within each that have the same name, such as:
Events > June 2013
Email Blasts > June 2013
Right now every folder and subfolder must have a unique name, so I have to do something like:
Events > June 2013 Events
Email Blasts > June 2013 Email Blasts
