I want to write a teaser that just shows on main page and is not repeated on the actual post. Is there a short code that would allow me to do this in version 5.1.2? Currently, teaserbreak short code will repeat the teaser on the post page. Of course that would be bad for readers to read repetitive text again before they continue reading the article.

I am aware I could use excerpt mode, but this would cause me issues with image formatting, unfortunately.

Thanks for your kind input in advance.
