Can we validate an expense report/expense creation before it got created

We're planning to use the expense reports and expense creation APIs. Since the expense report and expense creation having validation, we need to know whether we can do a post validation before it got created. This because even though there are validation errors expense report/expense getting created and there is no deletion API to remove invalid expense reports/expenses. Below is the APIs we need to use.
