1st, I have no idea how the 'upload' tool works, so this might not be
feasible...

Write a script which uses find (I love the tools from cygnus,
http://sources.redhat.com/cygwin/)
to locate all files in the jukebox created after the last time you
synced, (create a timestamp file in the process) then use the output
to have 'upload' upload the found files to the proper directory.

As Tony said, the functionality will probably be in 1.1 - but it will
probably also not (as the suggestion above) handle stuff you remove
from the 'master'.
