I don't think this is correct. I have many alerts in place that are
based on calculated metrics. The issue I have, however, is the
Adobe-provided calculated metrics do not show as available options
(i.e., only custom calculated metrics are available for selection).
Given that alerts now supports calculated metrics, it would be nice if
the Adobe-provided calculated metrics (e.g. Revenue / Visits, Conversion
Rate, etc.) could be selected. Being unable to do this, I'll need to
create my own version...
