Page mirroring

For lack of a better term, is it possible to have two seperate cards mirror each other?

For example, let’s say I want the same content in chapter 1 and again in chApter 5, but I don’t want to edit each manually every time I make a change to one or the other. I’d something like this possible?

There is nothing like that in Scrivener, no. We have it on the list of things to think about, since it is something that comes up now and then as a content request—i.e. where you need to print similar or identical data in multiple locations within the work.

Now, if you’re talking about organisational outline clones, we do have the Collections feature for that. For export however, Collections cannot add content, they can only define or subtract content (as a compile group or contents filter).
