iExpense - Expense Allocation - Project Allocations Page - Customize Field Labels

 In Internet Expenses and with that being used with Oracle Projects, the expense allocation portion of the expense report has a project allocations tab.  On that tab - there is a project, task, project expenditure organization columns that are visible.  **Note I set the Project Expenditure Organization to be visible.  I now want to update the column labels to be Work Order instead of Project, Account instead of Task.  Where in the OA Framework would I do this.  I see the personalize page and I am going through that but I am not sure where I would go to update
