Yep, was just stating my conclusion from the information you had provided as I wasn't able to see the screenshots with Google Chrome for some reason (they showed up okay once I switched to Firefox). I can certainly see the value in this, but I'm not sure on the timing for introducing it. As mentioned previously, if I just add this as a little popup dialog where you can enter the values and it populates the patch select command for you, that doesn't seem too difficult.
