JQuery :: (Validate) Specifying Error Placement For Only One Field

I have a form where I am using the jquery validation plugin. In that form, I have a date field that is using a jquery datepicker plugin so a small calendar gif immediately follows the date field. The date is required. The problem is when the field fails validation, the error
message appears directly after the date input pushing the calendar gif to the right of the error message. I know there is an errorPlacement parameter that you can use, but isn't that for every field in the form? How can I get the error placement to go after the calendar gif
just for the date field. Here is my test code. I am also using an AJAX form submission plugin. The name of my date field is startDate.

$("#myForm").validate({
submitHandler: function(form) {
$('#myForm').ajaxSubmit(function(){
alert('SUCCESS');
});
}});
