Running onSubmit validators for Linked Fields for array values

I have a Zod schema like this:

z.array(
  z
    .object({
      value: z.string(),
      primary: z.boolean()
    })
    .refine(
      ({ primary, value }) => {
        return !(!primary && value === '');
      },
      {
        message: 'Value cannot be empty if primary is not checked',
        path: ['value']
      }
    )
);

I have attached it to a schema like this:

const emailSchema = z.object({
  email: z.array(stringSchema),
});

I am using that schema on a form like this:

 const form = useForm({
    ...,
    validatorAdapter: zodValidator(),
    validators: {
      onSubmit: emailSchema
    }
})

On the form.Field for the email$[{i}].value i have this:

 <form.Field
      name={selector}
      validators={{
        onChangeListenTo: [`email$[{i}].primary`],
      }}
    >

The issue is that it does not revalidate the field when I select the primary checkbox on the primary field, because I don't have an onChange validator set for the form. However, I don't want the validators firing on every onChange event.

In the primary form.Field I can do something like:

 <form.Field
          name={`email${[i]}.primary`}
          listeners={{
            onChange: () => {
              form.validateArrayFieldsStartingFrom(`email`, 'submit');
            }
          }}
        >

But this doesn't give me as much control over which fields I want to validate. Ideally onChangeListenTo: would also have a callback option where I could specify the validation cause or something similar?

Start by tracing the form.Field validators onChangeListenTo and the primary field's onChange listener, then compare their behavior with form.validateArrayFieldsStartingFrom using the 'submit' cause. Define the requested callback or equivalent behavior so linked fields can be selectively revalidated with a chosen validation cause, and verify it with array fields using onSubmit validators.
