Yes, his campaign staff has a policy list. But does the man consistently stand by them and defend them each time? Nope[1]. Take the recent contradiction with Pence on Syria, for example. The traditional republicans are hoping he will implement their party's platform. But with a man so erratic and impulsive, and with mostly unchecked power of executive, how can anyone be sure?
