Automate reminder email to Customer for Overdue Invoices

Id like see a function in Reckon whereby when an invoice passes a certain "overdue " period (past its DUE date) that Reckon would automatically send a reminder email to the customer advising them that there invoice is now overdue.

As some users may not want to use this function it could be an Opt in /opt out function. Or perhaps a "button" that the user selects /deselects on the invoices you want this overdue reminder function to occur for . I think this would be a hugely valuable tool that would help use data already housed in Reckon to streamline and automate and part of the AR collection cycle.
