Hiding Author Name as according to Article parameter

Is hiding author name as according to article parameter possible?

I use News Show Pro to display 3 columns,3 rows, 9 articles' summary.

Under aticle layout > information order -> info format is set as By %AUTHOR.

Set as 2nd order, so format will appear as

- Heading
- By Some Author

But for some articles it is intentionally decided that the author names will not be shown.
ie: to show only Heading.

On click-through to the article, because parameters say HIDE author, therefor author name will not appear.

Any suggestion?
