Getting “parent pod” data when inside an EACH loop (pod template)

So here’s an excerpt from my pod template. It’s for a pod called “job-vacancy” and has a relationship field called prescreened user that is bidirectionally linked with the user (extended) pod.

[each prescreeneduser]
<h3>{@user_nicename}</h3>
<div>
	<a href="http://localhost/site/author/{@user_login}">
		<button>View User</button>
	</a>
</div>

<form method="post">
    <input type="hidden" name="user_id" value="{@ID}">
    <input type="hidden" name="job_vacancy_id" value="{@t.ID}">
    <button type="submit" name="update_user_pod">Shortlist User</button>
</form>

[/each]

I know that in this line <input type="hidden" name="user_id" value="{@ID}"> the tag {@ID} gives me the related user’s ID, since I’m inside the each loop. But in the next line, I want to get the ID of the job-vacancy post. Outside the each loop I can get it using {@ID} but I’ve tried every combination to get it inside the loop, and can’t – – {@t.ID}, {@d.ID} etc. How do I get the post_id that’s outside the loop?
