At my company we have pages, each one representing a physical item, and we have used the custom status ("/status [status]") within each page to denote the status for the physical object. Have have defined 8 custom statuses and applied them across a growing number of pages.
What we'd like to do is have a table on the parent page (the pages we want to scope are children to this page) that tabulates the custom status on each page so we can get an easy count of each status.
