Hi
There is not a way to remove a specific page from a default page flow report if you do not want to utilize segmentation filters. Even if you utilize segmentation filters that may have unintended consequences on the pathing data.
You may want to explore the options with Fallout or Pathfinder that allow you to specify specific sequences (although these are restricted in terms of counts). Also you could pull the Full Paths report and organize by desired line item of the results.
Best,
Brian
