I don't think so. But what I do is I use the default FSX flight planner (which is a somewhat painstaking process), load up the CS 737, and use the FSX Garmin G-500 GPS (Shift+6). The G-500 allows for flight planning, waypoints, and some older SIDS and STARS that for the most part aren't part of the current AIRAC cycle (1606).  :)
