How do I detect event ID 1, sensor shows down, event ID 2, sensor shows up?

Hi all, I can happily monitor a bespoke event log (Lync Server) for a particular event ID (25036) and the monitor goes red. I want that particular sensor stay red until a different event ID (25062) is encountered in the log. Is that something that can be done natively?

My current workaround is to trigger a script that creates a file when the first event ID is found and another that deletes the file when the second ID is found and have a sensor monitoring for the existance of that file for the up/down. I was hoping there was a more elegant way to do this.

Any ideas? Thanks.
