caption

String

The caption (display name) for the custom conversion column
This is constructed from:

• Conversion Rule Name + Metric Type("Conversions", "CVR", "CPA", "Value").
  E.g.
  "single ring page: Conversions"
  "single ring page: CVR"
  "single ring page: CPA"
  "single ring page: Value"
  
  In practice, each metric type is broken down into 3 entries, like this:
  
  "single ring page: Conversions"
  "caption": "single ring page: Conversions (Clicks)"
  "caption": "single ring page: Conversions (Views)"
  etc...
