When adding a multiple installment pledge in batch, you can elect to make the first payment along with the pledge creation.  This is done from the Revenue tab of the batch by selecting Payment.  However, if you click OK on the resultant payment form, there is nothing in the batch itself that indicates that a payment has been made.  You can see the payment on the record once the batch is committed, but the batch itself gives no indication of the payment.  This opens the door for user error.
