Is there a wordpress plugin to automatically set and highlight my brand name?

I am looking for a wordpress plugin for adding my sites brand name in a text with a button in the text editor. Instead of writing the whole brand name over and over again in my posts and pages and style it with <span> tags, this would really be easy, by simply pushing a button in the editor and add the brand name with correct styling.

Is there such a plugin or an add-on to a specific text editor in wordpress?
