Hey Gooner good question. You can break the reporting down to show stats by campaign by selecting from the ‘Breakdown By’ dropdown which is between the stats selections and the filter section. If you select Campaign from this list and run the report as normal you will see the results in the stats by campaign.

You can also select individual campaigns to report on by clicking Campaigns on the Filter section to reveal your list of Campaign ID’s.

I hope this helps answer your Q. If not let me know and i’ll try email you with an example specific to you.
Cheers,
