Check invoice date when sending invoices

It would be nice if harvest would verify the invoice date, when I press the send button and give me the option to cancel if the invoice date does not equal today’s date.

Our Use Case – Often, the person who prepares an invoice is not the person who sends it, and often it is sent on a different day than it is prepared (since invoices have to be reviewed/approved before sending). So, when an invoice is created, we don’t actually know the date that it will be first sent. The problem is that harvest populates the invoice date, on the date it is created — but, we mostly care about the date it is sent.
