How to change 1 element from 1 collection page without affecting the other pages?


I have a CMS for blog-posts. At the moment I have a hero-image where its set on COVER but I have 1 image on a post where this looks really ugly and I want this set on CONTAIN. But unfortunately all the other CMS pages will get set on CONTAIN as well. Which is not what I want.

I only want this specific image set on CONTAIN while the others on other pages STAY on COVER.

Anyone know how to do this?
