Customer Notifications for Split Payment invoices need to be different from the customer notification for non-split payment invoices!

We need the ability to add different templates.

And, those split payment templates need to be able to use the date and value of the different split amounts.

As a very minimum, we need to be able to include the date and value of the 'next' split amount (or 'Split 1').

Split payments are such a great feature! But, they are a complete pain without the ability to send a suitable invoice with the first payment value and due date included.

It means that the 'template' email has to be manually edited each time!

Please fix this!!
