Take the comps you want to make smaller and cheaper and copy them into a new text file with *begin* at the front of it. Then, open the tech gridder and select that file. Chose a naming scheme and the effects from the various tabs. Hit "grid now" in the Last tab, and it should output everything you wanted. It will create multiple Versions of each comp in the file with appropriate reductions based on tech level reqs.
