Enhance DMARC aggregate reporting

I would like to request an enhancement to the Sending Source feature. Specifically, there is a customer request to allow categorization of multiple Sender Hostnames (e.g., for internal use, forwarded emails, etc.) within the Sending Source view. When numerous Sender Hostnames exist, it becomes challenging to analyze data due to the mixed usage categories within the customer's environment. Implementing this improvement would significantly enhance usability and streamline analysis for our customers. I am confident that this feature would greatly benefit users, and I look forward to hearing your thoughts on this proposal.
