You're referring to the matching a single deposit in the Bank Feeds to multiple transactions in QuickBooks Desktop (QBDT), correct? If so, there's no need to split them. All you need to do is to receive the payments first and post them to the Undeposited Funds (UF) account. Then, deposit them as a single record into the right account.
Here's how to receive payment:
In QBDT, go to the Customers menu at the top to get to Receive Payments.
Select the customer's name and enter the necessary information.
In the Deposit To drop-down, choose Undeposited Funds.
