Button to add a field when viewing a report

I have a report which shows selected fields (of course).  I frequently find that I'm manually adding/hiding other fields when viewing the report, using the drop down menu.  Of course I could easily define variations of each report (v1, v2) which the various configurations of fields, but that seems duplicative. 

Instead, I would like a button that sits above the report header with the column name that adds a specific field to the report, like "Show Comments" for a comments field.  Ideally, it would toggle and hide the same field, but that's not necessary.
