Jobs in JC & PJ

Can you have a job setup in JC that's not in PJ?  We set up jobs for internal use that I would prefer not to see in PJ.  It's not really a problem when the jobs are sorted by Job ID, but when accessing some lists, especially through Outlook, they are in alphabetical order.  The only think I have come up with is to put a "z" in front of all the internal job names to move them to the bottom of the list, but would like a better solution if anyone has one.

Thanks,
