Certify has added a new parameter to the Custom Report Builder. Merge Wallet Items will merge any matching receipts and expenses into a single row on your custom report if selected.
If this option is not checked, the user will see two rows on their custom report for Wallet items; one for the expense, and another for the receipt image. By merging Wallet items, the report runner will have a better sense of the total spend currently in their user's Wallets.
