Pressure time history at specific points on a surface during unsteady simulation
 

I am looking to mimic the vertex monitor function in FLUENT using Fine Turbo 8.4.3. I would like to monitor the pressure at specific points along a body at each time step in order to investigate shockwave oscillation. Is there a way to do this without saving all the data required for visualisation of the entire domain? I would like to keep output file sizes to a minimum.
