If you are talking about sending an IFR plan via SD, you can't but you can plan anything you want and use it in flight. You switch from VFR charts to Airways in one touch of a button, you can also customize you IFR chart to show cities, terrain etc. It does not show SIDs or STARs, you have to pull up the AIP chart for that.
I use RocketRoute or Autorouter to plan/file the IFR flight plan and then import the plan into Skydemon for moving map, NOTAM, PLOG, met etc. If it is only a few sectors, I just rubberband it in SD
