FedEx SmartPost Support

Hi! I love TtP but was wondering if it would be possible for adding support for FedEx SmartPost, where the items are trackable initially by FedEx until they are handed off to the Post office (hence being given post office tracking numbers that don't show up with tthe post office for tracking until just before delivery.) If there was a way to implement that, that would be great!

Thanks again for a great service.
