Billing - Invoices UI

We've sent our first website live after going through the Agency Connect billing process but unfortunately the email receipt does not display any website details on the invoice.
Once we are in a position to put multiple sites live and receiving multiple emails without client details it will get very confusing which client is which.
Please could we include some basic client information in the receipt such as the website or client name?
Currently the only information I have available in the receipt is Invoice number, receipt number, amount paid, VAT and dates.
