I am able to add custom fields (text, images, etc) to the default Collections liquid file, but that content is displayed on every single collection that uses that template (all of them use the default template).
What I need to do is have different content for each collection. A simplified example would be uploading a picture of a car to the Cars collection page and a picture of a boat to the Boats collection page.
I’m aware you can add custom meta fields to products, but that option doesn’t appear to be available to Collections.
