Warning message on creation of IT0105 records

When I create a IT0105 record, subtype 0004 (phone number) for example and enter a phone number that already exists on another record I get the following message

ID/number already used for Person number nnnn. This is a warning message and I can return through it. Is there a way to make this message not display? I am trying to create records in IT0105 via a dynamic message and even if I use the /D in the dynamic action to perform the action in the background I still get the "ID/number already used for Person number nnnn" displayed. I do not want the message to display in the dynamic action so I would like to know if there is a way to suppress this message in all cases.
