If you do not want to "update" your existing UTM setup with the default UTM tracking parameters provided by Cometly, and you are already using Ad ID and Site Source in your existing UTM parameter setup, then you can configure the UTMs in Cometly to reflect your current setup.
To do this, simply select the UTM parameter that you use for Ad ID and Site Source from the dropdown next to "Ad Id" and "Source" as shown in the video above.
Please Note: You are not able to adjust the Cometly UTMs for the Google Tracking UTM template provided by Cometly.
