Reports: Option to add conversion event names in downloaded reports

Use case: Most non-ecommerce customers have more than one conversion event with some only being limited to lead generation while others related to revenue. It becomes hard to derive business value when there is no way to understand which campaigns were executed for goal #1 and which campaigns contributed to goal #2.

Solution: adding the option to download reports with conversion goals will allow customers to easily identify each conversion goal and derive business value.

PS - can be an additional parameter which is not part of the default reporting structure.
