Is it possible to match multiple card transactions to a single receipt with Expense Assisant

We are currently testing the expense assistant functionality and matching of receipts and card transactions with a small group of users. In this scenario, we have one receipt for flights, but it is broken down into six corporate card transactions. Short of emailing the receipts six times to link to the six card transactions, is there a way to link all the card transactions to the single invoice/receipt? I'm not seeing any way in the UI, or able to select a group of transactions and link them together. Is this a limitation, or something I'm missing in functionality or setup?
