I believe you can get the job to save the results from each node in an individual file. The way to do this is actually under the "Notifications" tab when scheduling the job. If you select "Save Results To File", it will prompt you by default to save the files to
C:\Program Files (x86)\SolarWinds\Orion\NCM\Jobs\${AgentIP}-${Date}-${Time}.txt
I recommend creating a unique subdirectory, as by default this will put all those files in with your jobs and job logs. I also believe you can choose to use the variable ${SysName} instead of ${AgentIP} so it might look something like this:
C:\Program Files (x86)\SolarWinds\Orion\NCM\Jobs\INSERT UNIQUE JOB NAME HERE\${SysName}--${AgentIP}-${Date}-${Time}.txt
When the job completes there should be a unique text file for each node this job was run upon.
