You used to be able to copy all panning, routing, plug-ins, volume, pans, etc... from the Audio Configuration window. But sadly, that window, and more importantly, the functionality of that window, was eliminated in version 8.
From your description though, it sounds like you might be better off saving a template with all your sends, panning, and reverbs in place.
You could even pre-label, and pre-color instrument tracks, so when, for example, you want to load that legato flute sound, you choose the audio instrument track that is already set up with that sound's settings in place.
That might be your best option for now...
