Purchase Register - Due date column

Hi 

Is there any way of adding the due date for a Bill onto the Purchases Register please?

Now that we are moving to a paperless office, I pay my suppliers from the register, but cannot see which ones are due. I have to run a report and put in excel - sort by due date etc... which is a bit long winded.

Or would there be a way for promised date to generate the due date automatically using the invoice/bill terms.  (And this could always be over ridden if needed).

Thank you
