remove author name or set constant

Hello,

I am having trouble changing the AuthorRule so that it either doesn’t show an author at all or displays a constant variable (Company Name) versus the post author name. The rule I have been trying to adjust is:

{ 
	"rules": 
	[{
    	"class": "AuthorRule",
        "selector" : "span.author",
        "properties" : {
        	"author.name" : {
            	"type" : "string",
                "selector" : "span"
             }
         }
            
   	}
 ]
}

Does anyone have any advice or insight on how I can accomplish either hiding the author completely or setting a constant that I define?

Thank you in advance,
Donna
