Change operating pressure without redoing simulation
 

I have done a time-consuming simulation, that finally converged, and it was done at an operating pressure of 100 Pa.
Now I have to append it to a second simulation, that was run at an operating pressure of 200 Pa...

Is there an easy way to change the results in my first Fluent simulation, such that the operating pressure is increased by 100 Pa, and the guage pressures decreased by 100 Pa, so that physically it remains the same solution? The difficult way is doing the simulation again at a different operating pressure, but I hope to avoid that...
