How do I prevent previous events from triggering new notification tasks

[Nick Robbins_1]

In CIM 7, I was able to add a condition to the event list so that it would only trigger if event was uncleared. This option doesn't seem to be present for automated tasks in SIM. Currently, once you create a new task that emails based on events, you get notification of all previous events in the database. How would I go about creating an automated task that would only email on uncleared (new) events? Thanks!
