Situation:

If the PR workflow has been rejected by any approver, the workflow will show [Submit] when back to the workflow requester. It is reasonable.

If the PO workflow has been rejected by any approver, the workflow will show [Resubmit] when back to the workflow requester. It is unreasonable, should be changed.

Error:

If the user clicks [Resubmit] in PO, the workflow will continue to the approver who rejected. It won't go from the very beginning, which means it may skip some conditions before.

Requirement:

1. The PO workflow should show [Submit] like PR.
2. The PO workflow should start from the very beginning.
