Thanks for this Matt!!  This seems to do exactly what I want.  I had a
bunch of misfires trying to set this up using the example from the
manual but I didn't want 'todo' as the selection criteria since I can't
match LEVEL=2 with that and I assumed that I could use any of the
Choice: values in the custom agenda commands when using a skipping
function.

I'm off to play with this new setup.
