In my project space, I have a list of pages - each page is a separate requirement. The content of each requirement is organized in tables. One of these tables on the requirement page has a row on which a macro lists incoming links to the page (specs pointing to this requirement). All links pointing to this page are listed next to 'PSD ID(s)'.
Below, the left table has no incoming links (no entries in the table), while the right table has 2 pages pointing to it.

At the project level, I need to list all of the pages for which this table cell is blank (meaning that no links are found pointing to the page).
Right now I'm doing this work manually (open each req, seeing if it has any links, create a list of pages with no incoming links). How can I streamline this?
