I have a bookmark to my Ubuntu-One folder in the sidebar of Nautilus, it would seem logical that it would be possible to drag and drop files and folders on top of this bookmark and have the dropped items copied to the Ubuntu-One folder to be synced to the cloud. However this does not happen, I can drop files and folders onto the shortcuts underneath "Computer" in the Nautilus sidebar but not onto anything that is a bookmark.

Is it possible to change this behaviour so that it is possible? Or failing that are there any possible workarounds to get a similar result?
