When creating BillPayments, allow Deposits to be a linked transaction
Using the QBO interface, when making a payment on a bill (creating a bill payment), you are able to link vendor credits and deposits via the linked transaction process. Unfortunately, when creating a BillPayment object via the API, you can not link a Deposit to the BillPayment. This feature would improve the API and make it more consistent with what the user expects from the QBO UI.
This is incredibly important to allow us to use the bill payment API.
