Your scoring is based on your credit file, and what is in your credit file is determined by what is reported by a creditors/debt collector.
Many items of information reported to your credit file, from the account itself down to numerous items if individual information, are retained in yourcredit file, theoreticalyl forever, until the creditor reports a specific deletion code, or the account has exceeded 10 years from closure.
There are no codes available to a creditor for retention of the information in your credit file, while also preventing it from being included in your CR..
To do what you suggest would, in opinion, be contrary to the integrity of the credit reporting system. The primary purpose of credit reporting is to provide those reviewing your CR with accurate information about your credit history. :"Hiding" information is not what the system is all about.
In fact, the CRAs, in their credit reporting manual, even consider the deletion of prior information by way of grant of a GW or PFD to be improper, and instruct creditors not to delete prior, accurately reported information based on payment of the debt, However, there is no way for the CRA to know the reason for deletion of any item, so deletion for whatever reason is just accepted by the CRA. You can get GW or PFD deletion, but such deletions are clearly inconsistent with the procedures established by the CRAs.
I would not make such a request in a GW, or even a PFD, letter.
