Pulling article readmore text for particles to use.

[dgrimey]

Is there a way to pull the "Article's Readmore" text into a particle? I see {{ article.readmore ? 'Read More...' }} returns 1 or 0 to indicate true or false. I am looking to set the Readmore text of a specific articles to use as the text I pull into a particle button. I am able to use "{{- article.title -}}", but would like more flexibility for SEO purposes. Below is a image of the particles options to bring in the article's content, and the "Readmore Label" puts the same label for each element. I want to specify the readmore text in the article.
