Report on customer vs teammate activity on Requests

Show which votes, Requesters, comments and Requests come from customers and which come from our own teammates, so we can prove the feedback portal is used by customers and not only by employees. Today no built-in report or export splits Request activity by role, and customers do not know whether anything was registered on their behalf. A customer engagement view (customer-submitted vs teammate-submitted vs submitted on behalf of a customer) would let product leads report on portal effectiveness internally. Amplitude is used for product analytics but is not natively supported, so native reporting is preferred.
