Excluding Sheets in a Report

I'm a little confused, in some of my reports under the "Where?" I have a checkbox option that allows me to to report on all sheets excluding the ones I have checked. I'm trying to build a new report that is going to report on a majority of our sheets except a select few.

I'd rather include them all and exclude the few rather than select all but a few sheets. However, that checkbox option is not available in my new report. So what logical process am I missing that allows for that checkbox to appear?
