I've been able to automate just about anything when it comes to the template here: https://cinemaelite.com/review/film/2018/06/sanpo-suru-shinryakusha/
I use Theme.co's PRO theme, and I've been able to use Custom Field shortcodes to my advantage, so I wouldn't have to go into PRO's editor again and again, unless necessary.
The problem here, though, is that I do still have to go in there to change the background image of my first section (the full-page heading and summary of the review, which is a story for another day) and for the author-title and date in both sections. Is there a way to have that done for me without the hassle of manually going in there and changing it? I mean, this would work wonders for now.
