Another crude but effective thought... You could create a "Report of
Reports", with no filter, ordered alphabetically by name (along with the
description, owner, etc.), and schedule it to be generated and sent to
yourself periodically (e.g. each month), and as each arrives, paste it
into a new tab in Excel, and name the tab to match the date (e.g.
YYYY-MM-DD). By doing so, you could then easily "flip" from month to
month to see which reports appeared (or disappeared) over time.
