I am not sure if this exists or not, the publishers offer me their template to write with, which is a Word Template with styles that they use. I want to use Scrivener to write my book as it is so much easier to manage the whole thing, but simply because the book has to be in the word document format at the end, it is just a bit more complicated. I would love to use Scrivener for that, is there an existing way to do that or if you can add this in the future release, that would be amazing.
We do intend to support stylesheets in the future, though how well that works with an external template from Word—I wouldn’t know. I’m not much of a Word expert, so I don’t know how easy it is to take a document with stylesheets and inject it into a pre-prepared template. It would probably just be a matter of setting up the style names correctly in Scrivener so that they match up with the template stylesheet.
Meanwhile, this isn’t really specific to Scrivener, but here are some general tips for converting a document without stylesheets to one with assignments.
