Single payment, multiple invoices in Kashflow

Sometimes you will invoice a client multiple times and they will make one payment.
I find this very hard to manage in Kashflow so I have recorded the process.

In the bank statement, select the bulk payment and Assign to Invoice, choosing one of the invoices.

Then go to the other invoice(s) and select Apply Credit.
It will allow you to select which Advance Payment (overpayment) you have made.
