Which AWS Cloudwatch API action generates the automatic dashboards?

Question

I was trying to generate the a dashboard with metrics from some AWS services. The faster way to do that is to go use the View Automatic Dashboard link that the services contain in Cloudwatch -> Metrics -> All Metrics -> Browse -> AWS namespaces -> [Service].

Then I noted that the metric PutRecords.Bytes: Sum is missing in the generated dashboard for Kinesis and a duplicated metric PutRecords.Success: Sum appears. The metrics GetRecords.Success: Sum and GetRecords.Bytes: Sum are included so I think that is a copy and paste error.

I don't see the feature in the AWS Cloudwatch documentation and I don't know where is the code for that so I was not clear where to report that little issue.

Then comes the question, where does that automatic dashboard generation happen ? There might be one API operation for that, but I don't identify it.
