I have a powershell component that is parsing large web logs. I'm calling TAIL to pull the last 2000 lines of the file to parse, but I'd love to pass the MESSAGE of the last poll (containing the time the last error was found) so I could query after that timestamp. Besides setting a text file on the server to track this, it would be great to be able to pass the last value (OR MESSAGE) to the component as an argument like I can for {$IP} and {$CREDENTIAL}.
