This isn't really a feature request. I just had an idea regarding the Rule action. I find myself having to create complex rules with the action quite often. After I am make the rule, I am typically making filters and reprofiling the data set to see where there may still be gaps that I haven't accounted for, or to validate the output from the rule I created is correct. It can be difficult to track what output is connected to which rule.
To handle the above, I sometimes duplicate my rule, and then change out the 'then' portion of the rule with an identifier so it is easier to detect which rule the output evaluated on. What if there was a setting in the rule action that tracked the rule ordering numerically (or allowed labels to be created) and generated a coupled helper column to make it easier to trace back where the logic is catching on?
