If I am using two weakauras Status: Cooldown Progress (On Cooldown and Not on Cooldown) to track the cooldown and availability of a spell can I track the duration of a spell. Say I want to track the duration of Pain Suppression, Power Word: Barrier, and Rapture before the cooldown progress shows how would I accomplish that?

Having trouble figuring out which way to trigger tracking the duration of the spells. Status or event?
