I was wondering if some could tell me if u can unregister for Full tilt points if u win a seat into a full tilt point mtt from a sit and go.

example would be if i were to use 300 points for a one table sit and go and the winner would win a seat into a 2,500 full tilt point super sat that wins a seat to a cash mtt. So once u win that 2,500 full tilt point seat can u unregister for it and the points show up in your cashier?
