Is it Possible for an Invoice E-Mail Approval Notification to State "Resubmitted" for a Resubmitted

Summary

I'm trying to determine if there is a way to show "Resubmitted" in the e-mail subject of an invoice approval e-mail.

There are some cases in which there are 4 approvers in an invoice approval workflow. In some cases the approval moves through the 4th approver but is then rejected. When the user re-submits the invoice it then needs to go through the entire chain again. The approvers who are 2 and 3 may not know it was rejected from the top and so when they see the approval again it looks like a duplicate and they may then reject or ignore it.
