You can't. I think it's unfortunate, but other than writing support, you can't do anything. You'd ask support to change the status back to pending for you.

When they reject it, you'll be able to attach the property release without re-uploading - status goes back to pending your edit. My general experience on these partial resubmits (for a forgotten model release in one case and a request to change the category in another) is that they don't take as long as the 10 days or so for the first inspection.
