auto submit form once?

Constantech added this great autosubmit method as a tip/trick:

<script type="text/javascript">
jQuery(document).ready(function($){
var delayMillis = 5000; // 5 seconds
setTimeout(function() {
$('#form_edititem button[type="submit"]').trigger('click'); // replace edititem with form key
}, delayMillis);
});
</script>

Is there a way to adjust this to autosubmit a form entry only the first time the entry is created/submitted? I have a form B entry created automatically from a Form A creation/submission. I just want the specific form B entry to autosave the first time only. I then need it to be editable and save normally with the usual button click afterwards....??
