Hide server activities from reporting?

In K2 reports, when we drill down to a specific process instance and view the reporting data that displays each activity, is there a way to get K2 to NOT show all the activities that were performed by the server (i.e only display activities that had humans as destinations). We have many activities in our process that do nothing more than update SP lists and send mail, and seeing these in the process reporting creates a cluttered view. It would be nice for the manager or user that is reporting on a process instance to be able to only see metrics on human involved activities.

Thanks,
