Is there any way to document in the report what your query is about/doing/etc.?
You can add a new report tab and add a new free-standing cell (Figure 1), and then add documentation in that cell (Figure 2). Or you can just insert a blank cell onto an already existing report and fill it in with documentation. Here's how:
