How to kill long running scheduled reports?

We had a long running scheduled report on NTFS permissions that we wanted to terminate.  Looking under the Scheduler History i can see the report in 'Processing' Status.  But there is no option to terminate or stop the report.  My only solution was to disabled the report schedule and then restart the ADManager Plus service on the application server.  
is there a way to terminate a long running scheduled report without having to restart the service?
