Prior balances with no current time charges should print automatically as part of the batch

I have just discovered that a number of past bills, unpaid, did not and apparently do not print as part of the current month's batch if there are no current time or expense charges. This is insane. Why should we have to "search" for prior unpaid bills and create a separate statement for them? ANYTHING unpaid should print in the current batch! This flaw in bill4time is a huge pitfall and allows bills to go unpaid and unnoticed. WHY would you design the software to allow this?
