How Do I Update Plug-In Across Entire Website?

Hello!

I am building my first website with Wordpress. I am current using OceapWP Theme, Elementor Pro (with elementor add ons) page builder. I would like to sell a "Featured Facebook Ad Space" under each blog post, however, I would like to update that Facebook post with current, future, AND PREVIOUS blog posts (across the website) .

Is there any way I can paste a code or have the featured Ad space be updated on current, future, and previous articles? It now only does it for current and future articles.

Thanks in advance!
