In a job cost scenario: is there any way to generate a cash flow report (cash paid in - cash paid ou

We are in construction and each one of our jobs is associated with a business unit (i.e. record in the F0006).  There has been multiple requests for a report that shows the cash flow calculation (Cash Received to Date – Cash Paid out to Date = Cash Flow Position) for each month of the job, as long as the job is in existence.  There seems to be a cash flow report for the company (i.e. a record on the F0010 file), but I cannot find one for the job.  Is there one out there?  Maybe a way to generate one in a World Writer?
