Reconciling Many Meal Charges to a Single Per Diem Expense Line Item

Content

My client is a consulting company that's looking to integrate corporate card with their existing Oracle Cloud Expenses functionality. The client works some projects where they must report meals as actuals, or per diem meal rates. When reporting per diem in the expense report items, we want a single line item per day representing that days per diem amount used. When using the corporate card, all transactional detail comes over, and we don't want that. Is there any way to merge multiple credit card transactions into a single expense report line item? Or has anyone else ran into this issue?
