Subtract data sets in transient RF ewt simulation

I want to run two simulations: one with d33 = 1e-17 and another with d33 = 0. Then I would like to subtract the results for Ez. It would be great if I could also subtract the results of the domain point probe that is defined in Comsol's model (in order to FFT the transient data at that point).
I have tried to define a parametric sweep over d33 with two values (0 and 1e-17). Then I attempt to join the data sets. The issue is that Comsol will only join data sets at one time step, so I would have to create a join data set for every time step. The other problem is that the parametric data set does not encompass the domain point probe, so I would not be able to FFT the data sets unless I store every single time step taken by the solver.
Perhaps Matlab? I have no problem extracting the data from Comsol and then subtracting the results, but I am not sure how to convert the result into data Comsol can use for functions like mphplot.
Thanks for your help.
