UTM TAG in Contact Details

Hi, i try to add the UTM Parameters that comes with Formular to the contact.

I have created a Mautic Form with capture UTM Parameters.
When i send the data as email i have the correct URM Parameter in email with that line ref9 : {formfield=ref9}

But i would like to have UTM saved in Contact Details when they submit the Form.
I did not find the solution, but maybe you know how to do that.

Best Regards,
