Add Created by API User filter

When investigating API user activity, Marketo currently only provides visibility into the number of API calls made by a given user. However, when trying to determine what a specific API user changed or created on a person record, the process is not straightforward.

Adding a dedicated Smart List filter or activity constraint that allows users to identify actions performed by specific API users would be extremely valuable for troubleshooting, auditing, and debugging purposes. This enhancement would significantly improve visibility into API-driven changes across the platform.
