Sorry, I have deleted my first reply. I re-read your question and realised I had misunderstood. You are looking for a “universal” option to hide the country across all of kiwitrees, to match the option in the two “fancy” reports.
But do you really mean everywhere? If not, where should the country be included and where not? It would not be hard to add it everywhere, but is that really a good idea? Of course, it would be an option only, but …….? Perhaps others will say include it here, but not there, and all with a different idea.
