Ufortunately you cannot pickup which swept files to save, since after simulation the sweep will reload the simulated files to pickup the results.

What you can do is: reduce the number of sweeps, say 20 by 20, find the better parameter ranges and refine the sweep for another 20 by 20.  the drawback is it might miss the best parameter range. However for only two parameters you could run optimization directly, Unlike sweep, the optiization does not save files for each generation, which can save hardware space.

You can also file a feature request: give an option to save only one set of swept files (up to the number of capacity in "Resources" or concurrent simulation) , meaning, pick up the simulated results before next sweep.  Please refer this post to write a request.
