I'm using Trello to outline a story. Imagine each chapter is a LIST. And within each list, each CARD represents a SCENE. But sometimes there are, say, scenes within scenes, like a flashback. And I want that scene within a scene to "roll-up" into its parent card, so I only see that flashback scene/card once I open its parent card. In other words, it doesn't appear on the LIST unless I open its parent card. I basically am looking for indents, nesting cards, roll-up functionality.
I tried adding the "Hello Epics" power-up but that does NOT give me the functionality I'm looking for, which is a streamlined/neat/uncluttered/top level view of the organization, not all the details within. Is there a way around this???
