Not yet but could be a nice addition.
I agree with this. It would be nice to have a notification option to let you know of long-running jobs. A generic 'RunTime' notification option, with a variable/option per job or task to set what you consider a safe timeframe (1 hour, 3 hours, etc..) so the one notification area would use the per job/task info as to whether it should trigger. We can already do a Timeout based on a value, a notification (that doesn't kill the job/task) would just make it that much better.
