No, currently this is not possible. If you want to expand on your Capture Duo sessions it is recommended to transfer them to Studio One on your Mac or PC computer. There you can continue recording new tracks.
This feature works with all versions of Studio One (Free, Artist, Producer, Professional) as long as you have installed Studio One 2.6.3 or later.
