AR - Direct Debit by way of payment schedule

Hi all, 

It's been a while since I've posted a discussion.

I have a specific requirement from our business to allow for partial payment of an open item within Direct Debit by way of a payment schedule. 

This would work along the lines of :

-Open item Balance $1000 billed quarterly

-Direct Debit agreement set up with customer to allow $100 to be Debited from customer's bank account on a weekly basis.

I am aware that you can make partial payment through the Receivables - Update Direct Debit worksheet, but this would require manual intervention periodically which the business would like to avoid.
