get ManagementObject from EventArrivedEventArgs

Platform: Windows XP Profressional with SP3, .NET 3.5

I'm using the ManagementEventWatcher to monitor new instances of Win32_PrintJob.  I want to be able to quickly use the ManagementObject->InvokeMethod() method to pause the new print job.  I want to confirm that there is no way to get the ManagementObject from the EventArrivedEventArgs, and that I have to make a new ManagementObjectSearcher object and query for a ManagementObjectCollection as follows:

// Pull out JobId from the ManagementBaseObject inside of the event arg

System::String^ jobid = (

	(System::Management::ManagementBaseObject^)in_event_args->NewEvent->Properties["TargetInstance"]->Value

)->Properties["JobId"]->Value->ToString();


// Query for ManagementObjects with the jobid (should only be one)

System::Management::ManagementObjectCollection::ManagementObjectEnumerator^ moe = (

	gcnew System::Management::ManagementObjectSearcher(
"\\\\" + System::Environment::MachineName + "\\root\\CIMV2",
"SELECT * FROM Win32_PrintJob WHERE JobId='" + jobid + "'"

	)

)->Get()->GetEnumerator();

moe->MoveNext();


// Get the object and pause the job

System::Management::ManagementObject^ mo = (System::Management::ManagementObject^)moe->Current;

mo->InvokeMethod( "Pause", nullptr );

I'd really like to avoid having to re-query inside of the callback, but as far as I can find, I have to. 
Is there a way to get the job's ManagementObject from the EventArrivedEventArgs?  Alternatively, is there a better way to watch for and pause print jobs all together?

Thanks!
