Track UTM parameters without form fill-out or Javascript

It would be very helpful to be able to track lead source information via UTM parameters in a more simplified way. Currently, you either need to: 

- create a form with hidden fields for the UTM parameters to pass onto Marketo

- write Javascript on the landing page

The limitation of creating a form is that in the case of a highly targeted social ad campaign, where you know exactly the people you are targeting, you don't want your leads to go through that extra step of a form fill-out.

Then the only other solution is Javascript which adds complexity and not everyone has Javascript capabilities on their team. 

Is there a way for the Munchkin code to pick up the UTM parameters/identify a lead's source and directly feed the information to Marketo?
