Shoppers' View is a company that requires a comment for every "No," "N/A," or "Negative" answer. When I edit, to make sure there is a comment for each question, I scroll through the report and copy and paste each question that is answered in the negative into a notepad document. Then, as I'm editing, I delete the question out of the notepad when I read a comment that addresses it. At the end, I'm left with a list of the questions that weren't addressed (or, if I'm lucky, a blank notepad).
After editing, I do the same when I shop and write reports (make a list in notepad, and delete it as I write a comment to address it).
