Thank you for the help Matt! coglogoinsert works perfectly for what I
need. The only problem is, I'm still not sure how to combine the two
streams. Do I need more than one pipeline? If I do, how do I merge the
results from the two? Any help you could give about that would be much
appreciated. :)

Thanks again,
