How to manage multi-payment arrangements

We now have a growing number of customers who have several simultaneous payment arrangements, i.e., get HB four-weekly but pay the HB shortfall by monthly DD, or get a rent APA from UC monthly on 27th but pay the UC shortfall monthly of 12th. These cases continually appear as breached arrangements but they are paying correctly - it is getting more common to have cases like this so if the correct total amount due per month is covered in the calendar month, they should not appear on the worklist.
