tl;dr: Does Ubuntu One detect renamed synced folders?

I'm trying to rename a large synced folder ('Sync locally' checked) outside of Ubuntu One, but still inside the home folder on Windows. Attempting to do so results in an error message:

Cannot rename foldernamehere: It is being used by another person or program.
Close any programs that might be using the file and try again.

Quitting ubuntuone-syncdaemon and renaming results in Ubuntu One not finding the synced folder (folder in ubuntuone-control-panel-qt becomes grayed out). Ticking 'Sync locally' again causes Ubuntu One to begin downloading the synced folder with it's old name and ignoring the renamed folder.

Is there any way to locally rename a synced folder short of reuploading the entire folder under a new name?

Thanks for the help!
