Payment Thank-You Question

Payment Thank-You Question

Hello,

When a client sends one payment covering say 3 Invoices we now find it easier to record these by clicking on "CUSTOMERS" then "RECORD PAYMENT"
This way we don't have to bring up each Invoice plus the client only receives one "Thank You" email. The problem is how do we get the thank you email to include more than one invoice number when our thank you email reads like the following:

Dear %FirstName%,

This is just a courtesy email to let you know that we have now received your remittance against Invoice %InvoiceNumber% dated %InvoiceDate%.

Many thanks

Brian
