For the record DPP44's have dropped way down in cost. Go see your favorite Retailer, be nice to them and they may give it to you for less than 100 smackers. It is the ONLY way to do what you need to do with a D1000.4 unless you add another 1000.4
Technically my way will work, but I'd go for the 44 switch. If you think that you may ever have a service tech out to your house doing it my way is just asking for trouble.
