@DanCross this is a great idea. I just sent it over to our Data Connector Team. We will continue to monitor up votes and comments on this thread.

You are right this is hard to do today. I can see how this would be helpful. We'll keep an eye on the number of votes. Couple of questions.* Are you trying to use this in a segment?* How do you want to view this information?

With the new update to calculated metric we are now able to create this.

This was added a few months back.

This is available in Report and Analytics now.

With the latest release of Adobe Analytics we have included a count function which will count the rows in a dimension for a given metric. This combined with some clever segments should allow you to get at what you are trying to do. Just remember to use Unique Visitors as you metric.

With the latest release of calculated metrics you can now create segmented metrics for new or repeat visitors (you can define them however you want, most people define it as visit number > 1 and visit number = 1). This can then be applied to any report.

Calculated metrics can now be used in Anomaly Detection.

The totals rows should now show up for Calculated Metrics with the latest release of Adobe Analytics.

With the new release of Adobe Analytics we implemented a new builder to replace the one in the admin console and it definitely has friendly names.
