Feature Request: Add functionality to specify if repeated alerts are wanted when a scheduled Job fails.
Example: Company ABC is running a job with 6 executions every 1 minute. If their database server went down or something prevented the execution in that appointment block from completing they would still receive a notification every minute. This is because each appointment's job's execution is unique and separate.
Now if they scheduled a job to run every 5 minutes, and the same failure occurred we would send one notification and not 5... then on the next appointment that counter starts over.
