Vacation Rule to Surpress FYI emails from iExpense

Our executive team, and VP's do not want to receive fyi emails coming from iExpense anymore. We are able to do this using the workflow administrator -> administration -> Vacation Rules -> Employee -> create rule - item type (expenses)

We then choose notification and search for "OIE_CC_DIR_MANAGER" (Expense &DOCUMENT_NUMBER for &EMPLOYEE_DISPLAY_NAME (&#HDR_DISPLAY_TOTAL) has been submitted to another manager for approval)

Then we click "close" for the response. We have done this for half of our leadership team. The other half we don't get an option to choose "OIE_CC_DIR_MANAGER".
