Ability to filter out sequence related emails from all reports in terms of activities

For further context, we use the sales activity report to help monitor outreach/activity by sales reps. Presently, the report includes all emails, including those sent as a sequence by Marketing on behalf of the rep (as 1:1 email). Unfortunately, this slants the view and makes the raw data of minimal value as the rep is not driving these emails. Being able to filter out those sent via a Sequence would enhance the value of the data and more truly reflect each rep’s activities.
