PeopleSoft Expenses 9.2 PUM52 - approval of expenses

Our workflow is configured such that it goes to a project coordinator for expense approval.

The challenge that we are facing is that if the project coordinator enters an expense - we get an error - "You are not authorised to approve or modify a transaction that you submitted" - because expense module does not allow for approval for same person - is there a workaround to this that PeopleSoft offers.
