AR Transactions not to appear on Aging Report

Hi,

We have a requirement to add customer transactions into an existing operating unit that are to be separated from other transactions and to not appear on the standard Aging Reports.

The setup we are aware of to support this effort is:

Transaction Types Form, Open Receivable = No (not checked)

However, the question was asked if there is any Customer setup that can be used as an alternative.  This is because the separate group of transactions will be for one customer at this time.  I checked the Customer forms and did not see a field to support this, but just wanted to ask the community if they had information regarding setups other than Transaction Type that could remove transactions/customers from the aging reports.
