Renaming Labels via Embed Script in Forms 2.0

Hi Guys,

i'm using the forms 2.0 to handle all contact sales forms on our website. To only use one form in Marketo, i'm overwriting the specific params for each product inside the embed code, which works very well:

<script src="//app-sj04.marketo.com/js/forms2/js/forms2.min.js"></script>

<form id="mktoForm_XXXX"></form>

<script>

    MktoForms2.loadForm("//app-sj04.marketo.com", "XXX-XXX-XXX", XXXX, function(form) {

        // Set the value of the Phone and Country fields

        form.vals({

            "Country":"USA",

            "Lead_Offer__c":"Contact Us",

            "LeadChannel__c":"Web Form",

        });

    });

</script>

What i want to do now is to overwrite the existing labels to make the form work on our multilingual website.

The question is: is there any function to also overwrite the default labels via this embed code? is there any function like label.vals ?

Thanks for your thoughts.

Cheers

Ralf
