FCCS Alert Type for Completing a Task

We have 100+ tasks in our Task Manager outlining our close and forecast processes and we are wondering if we can set an alert on a specific task that will then trigger an email notification once that task is submitted/closed? We have been playing around with 'Alerts' but it doesn't seem that these Alerts are intended to be used this way

These triggers on specific tasks would be extremely helpful for end users to know when a task is completed and when they can begin their task.
