Move all Print Jobs to "Unassigned" for a single job

This is has got to be pretty simple but I got a "block"
on how to do it.

I have a "end of day" job that has many print steps using
various print file names and short of doing a ovrprtf on
each step, isn't there a way to do a ovrtprtf for all
print jobs in a CLP ?

This CLP probably has 30-40 steps and many do a print
job, soooooo how not to miss any ?

I would like to send all jobs to the "unassigned" outq
and ideally put them all on hold.

I was thinking along the lines of a CHGJOB outq(zz) or
somthing along those lines.

That would send them to a "unassigned outq" but that
would not put them on hold. The "put them on hold"
may be the tough part.
