Extraction conditions for PDF Reports

For subdomains that have been set as Flagged from Managed Domains, it is possible to exclude them from the target by filtering them on the dashboard, but this is not possible in PDF Reports, and data including the subdomain value is extracted. I would like Flagged subdomains to be excluded from PDF Reports. Also, there are many cases of spoofed emails being sent from subdomains that do not exist, so if possible, it would be better to have an even worse flag than Flagged that would prevent future references after being set in Managed Domains.
