Due Dates showing on Parent list

It would be great to know which amounts are truly outstanding and which are not yet due. From the parent screen (or student for that matter) we can only see the amount owing.

Enrolments happen constantly throughout our Season so when we are in the 3rd week of term and all the pre-term enrolments are due, we would like to be able to send the invoices to only those with an outstanding balance, without including all recent enrolments. Especially when we need to use stronger wording on the invoice (Text at Top of Statements).
