Problem pre-filling data grid elements

I have a data grid element where people can add x number of text fields, while I can pre-fill basic fields the grid does not behave in the same way when trying to pre-fill some of the form fields on page load.

  var form = new FormioForm(document.getElementById('formio'));
  form.src = 'path-to-form';
  form.submission = {
      data: {
        addressStreet: '123 Something Street', // works
        addressSuburb: 'Somewhere', // works
        addressPostcode: '40000', // works
        licencePlates: [
            {
                textField: "abc123"
            },
            {
                textField: "another"
            }
        ]
      }
    };

The address fields prefill and when doing a console.log on form.submission after adding some data grid items through the form itself it comes back in the same format as the pre-fill object.

Does the data grid component have any pre-fill ability at present? Is it limited to basic fields?

This shows an example of a data grid being pre-populated with data.

Are you experiencing something else where something like this usecase is not working?
