The “Not in” filter is the most significant and helpful feature for us on the new dashboards, because we currently use a painful manual workaround to identify customer engagements across all types of metrics.  Unfortunately, this filter does not work on the new dashboards.  If I select “Not in” and Custom Role = “Employee” I get wildly incorrect results (major undercount).  I have logged a case for this and submitted a video showing the behavior.  I’d love to get an update when this is fixed as this is a major blocker for us.
