Please allow us to add a payment reference to an Invoice/Receipt/Bill when publishing it as paid.

Allow us to assign a Default Payment Reference to a Payment Method that then pre-populates the Payment Reference for All Bills using that specific Payment Method, the user can then manually update each invoice if a change needs to be made or can add a Payment Reference when editing the Invoice.

When the user submits a document as paid to their accounting package it uses this Payment Reference as the Payment Reference for the payment created in their accounting package, this will help the user with their reconciliation of payments to bank transactions.

I have mocked up an idea of how I'd expect it to look/function (I have highlighted in yellow the parts relating to this feature)
