Routing comes from your flight plan, the only thing mode S would show for your aircraft is the selected heading and level (if you have autopilot). for example at swanwick it would go onto the system and we'd be able to see your way points. VFR flight plans, usually not unless you're speaking to us and we've paired your flight strip in the system up with the aircraft.
