Hello Aaron,

qjackctl has an excellent solution for that. There is a patch area, call 
it from the button at the bottom, below stop (don't know the english name).

Create an outgoing patch from the PulseAudio sink and an ingoing patch 
to the system outputs, and connect them. They will connect in serial 
order. These patches accept regular expressions for the jack ports, for 
example:
     out_port\.[0-9\.]+

Save this patch and activate it. This will create the right connection 
on demand. This works for many different audio scenes like magic. It's a 
very smart concept.

(As a side note: I only have to deaktivate the automated patching of 
qjackctl when I do sond export with ardour. There seem to fight some 
deamons :))

Regards,
Georg.
