I suppose you’re referring to gclid parameter. Piwik PRO already tracks that and uses it for the purpose of integration with Google Ads and traffic classification (if gclid is present then automatically google/cpc is set up for source/medium dimension).
However, it’s not possible for the Piwik PRO tracker to read out of gclid what are the UTM tags set up for the ad so if you want to have campaign names in reporting instead of “google ads unknown” it requires adding UTMs explicitly.
