In funnels you can hold a property constant to ensure that each event stage of the funnel has the same value of a given property. I would like to inverse that, so that the value of a property must be unique. For instance, I want to see how many unique content items a user opens or completes in a given timeframe. Dev team has explained it’s difficult to fire these events only for the first instance. And the Historical count in Amplitude does not help this use case, because I don’t want to specify what the values of the property are, I just want each value to be different than those associated with the previous events in the funnel.
