Updates from the request transfer to the project.

When we convert a Request to a Project any conversations that were in the updates transfer over to the Project updates page. Which would be ok but it allows for the people in the project to reply to those comments from the requestor. We try very hard to keep all of the communication between the Requestor and the Project Coordinator. And we are trying to keep all Requestors out of our Projects. They only have access to the Requests.

Is there any setting that would prevent these updates from transferring?
