When you switch the invoice from trade to non-trade, it should show up in non-trade list. This is not happening at this moment. I then have to go and find said invoice if I didn't copy it to my personal file. It would be a much cleaner list and no duplicates vouched and stored. This would just be for convenience, not really needed. Also the other way around doesn't do anything. It keeps the invoice in the non-trade list.
