Node Specific "Comment settings."

Comment settings in “Permissions” applies to all content type. I want node authors of only one of my content type to have permission to “Administer comments and comment settings”. This way node authors can enable/close/hide comments as they see fit on that one specific content type. Don’t really want project/nodeaccess. I’m hoping for a more specific existing module, or PHP snippet for template.php or custom module. 

Appreciate any help.
