Default Titanium backup: how can I sync *from* Dropbox/Box.net?

Hi,

I backed up my backup using Box.net and Titanium Backup. Synching To Box.net works fine but how can I restore FROM Box.net? In my eyes there would be no sense if I have to leave the data on my device and the cloud storage. Eats local memory and doesn't help me when the device is lost.

Thank you for support.
