Currently, we are manually documenting the names of excerpts on our pages and where across our documentation those excerpts are being used. That way, if it's ever an issue that the parent page is updated or the excerpt removed, we know exactly what other content might need to be updated to ensure those changes make sense.
Some recent content improvements are likely going to drastically increase the instances of excerpts being used across our content, which is going to make this manual tracking unwieldy at best.
It seems silly that there isn't a macro that can be inserted into a Confluence page that reports on excerpts in a certain Confluence space and tracks which other pages that excerpt is shared to.
Does this exist? If yes, what is it called or how do I do it?
