Posting dates on Collection letters should be flexible to allow for the Actual posting date of the collection letter be reflected when posting via a recurring Batch Job.

Currently in the system, the posting date is either gotten from the date the recurring batch job originated
i.e. When a blank date is used for recurrence posting, it uses the FIRST date of posting and sets that as the value. Each subsequent posting uses that same value.
OR
At the point of creating the recurring Batch job, the Posting date be specified which in turn makes the posting date rigid and subsequent posting uses that same value.
