Clarification on quantity and unit price for Late Charge Transaction

Summary:

We've enable Late Charge at the Customer Account Profiles and using Late charge Type as Invoice and creating Late Charge Transactions for Overdue Invoices and Late Payments of Customers.

After running Create Late Charges Batch Job, Late charge Transaction is created for the customer but not with the original quantity of the Transaction instead with the number of days Transaction is outstanding in quantity field.

Can you please clarify is there any setup with which we can control the quantity and unit price of Late Charge Transactions?
