Multiple utm_source parameters in visit

How does Matomo’s Campaign Source reporting handle two separate utm_source values? ie we have the clickthrough URLs on our paid search campaigns tagged with utm_source and utm_campaign, but we also have certain CTAs on our homepage linked with utm_source and utm_campaign - so how would it handle reporting the utm_source when a user comes to our homepage from a paid search ad (utm_source=googlecpc) and then clicks a CTA on our homepage with utm_source=homepageCTA?

Would the source be ‘googlecpc’ or would it be recorded as ‘homepageCTA’?


I think I have tested this in the past at the first occurrence of the UTM in the URL is used, you can’t have multiple campaign urls in a visit.
