A means of getting parent doc titles into the header

I’m doing a comic script, but I’m separating the dialog and captions from the scenes.

I’m wanting to print only the dialog files for each scene, but want indicators at the top as to where they are coming from because I named the dialog files just “Dialog” for simplicity. I would like some markers on the page for organization.

Is there a way to get the title of the parent document (the dialog file is a sub to it) in a replacement variable? The chapter it’s in? Anyway to get this into into a doc without hand typing it for each and every page?

Can you set up the parent to print just its title, no text, in the Formatting pane? Then it would work more like a traditional “chapter title” in the sense that you have a title somewhere, and then stuff that is “in it”, then another title to mark a new section with its content to follow.

Otherwise, there will be a <$parenttitle> token in the future that should help with this.
