Elvanto's current form system lacks the ability to prepopulate form fields through URL parameters. This feature would be highly useful for many scenarios, including matching a form to an existing record in the system.

The requested feature should allow for prepopulating form fields by passing data through URL parameters, which would enhance the form-filling experience and reduce errors. For example, a form could be prepopulated by using a link like this: https://your_church.elvanto.com/form/your_form_id?field1=value1&field2=value2.

I kindly request the Elvanto development team to consider adding this feature to the system. Thank you for your consideration. Please let me know if you require any further information.
