I'm trying to have a setup like this with the Dawn theme
1: Custom content
2: A collection
3: More custom content
But custom content unique for all my collections and that's my challenge.
If I use the custom block, the content is inserted on all collections, because of the way collection pages are generated, and collections are inserted by my understanding. But I'm feeling I'm missing some basic stuff here, but I can't wrap my head around it.
