Welcome to the Q&A Forum

Hi Richard, Thanks for writing in with a great question. Unfortunately, at this time we don't have a way to track more than three search engines per campaign. There is a feature request for adding more search engines to campaigns in our Feature Request Forum already, but it has only received on vote so we haven't prioritized this functionality yet. I would recommend adding your voice to the forum here: https://seomoz.zendesk.com/entries/484362-Add-more-than-3-search-engines-per-campaign, since the Product Team uses the forum to make decisions on what features to add or prioritize. I hope this helps. Please let me know if you have any other questions. Chiaryn Help Team Ninja
