Hi there,
WordPress uses the_title() function to output the title. That function has the_title filter, however WordPress uses the same filter for things like widget titles and menu item titles, so it’s nearly impossible to target the content title, unfortunately.
Your best bet would be to disable the standard title and add your own title function into the page using Elements. That way you could conditionally load the title based on your own parameters.
Let me know if you need more info 🙂
