Is there any way on the Omniscope Scheduler to stop XMLs droppped into the Scheduler if they take longer then a fixed time period to run?

I know there is an option in the Scheduler that automates the XML Actions file, however if you drop the xml into the Scheduler manually or through a separate automated file writing process.. Is there a piece of code I can add to the XML Actions file itself to stop the task if it takes longer than a fixed time? Thanks - Ben
