Mass Updating Form Fields

Hi friends,

There are times I get tasked with updating form fields for all the content we have on the website. However, because we are using non-Marketo landing pages and we want each respective PDF to open in a new tab upon the form submission, we don't have one global form set up even though all the fields are identical.

Is there any way for me to do mass updates across a set of forms anytime we want to update them or there's no other option but to make individual updates?

Thanks!
