Yes, section access would do that. Note that section access actually removes all records that are not related to the value specified in the reduction field. Check this post and this thread and this one. There are many others in the forums, and some descriptive documents (and videos in the "Documents" section in the "Browse" menu above) that you can peruse to understand better how this works. These examples are actual issues, so they may help you get the point.
Hope that helps.
