Letting only certain users see attachments


Hi everyone, I am wondering if there is a way to hide attachments from certain users until they have been reviewed. I am using smartsheet for a PBC list and want people to be able to upload items assigned to them, but don't want the external party to be able to see the attachment for that row until it's been reviewed. Is there a way to have it not show attachments for a row until that row has been marked reviewed or something like that?
