Is there a command similar to on("change:<attribute_name>) that works with <roll_name>. I'm trying to find a way to project on sanity. The idea is that I could reduce my sanity loss projecting on one bound (reducing it's value by 1d4). To do so I need to have a temporary value for the sanity (done) and modified it with the value of my roll. However, whatever I try I cannot save the roll value as a variable to be used in modifying other attributes when a dice is rolled. Note: I'm trying to do it using only the character sheet script
