Can we disable duplicate expense item check while entering the expense?

Summary: We have a requirement where we are importing expense reports from another system and want all those expenses to go through Oracle Expenses. Expense approval as well as auditing would be happening in the other system so we want to auto approve all the expense reports as soon as they are imported in Oracle Expenses which we have taken care of. we have not enabled any audit roles so its not going to auditors as well.
But while testing when we try to create a duplicate expense item its giving Duplicate Expense item warning window. Since we are importing the expenses through API this warning popup is causing issue.
