Allow us to organize vendors in order tracker by placing closed POs at bottom of page

Would love the ability to move PO orders in the order tracker around so that I can have all awating items together, shipped items lumped separately together and can move all closed POs to the bottom so they don't clutter the items I'm still tracking. Only having them organized in alphabetical order is only useful before anything ships. Would be great if we could drag the POs around like we can drag the tasks around to organize them. Maybe make it so all closed POs automatically drop to the bottom of the screen??
