Flow heading overrides in templates

Hi
I‘m using the new feature „flow heading overrides“ in a book that I‘ writing.
My question:
Is there a way to make an template with all my overrides ?
I tried, but without the overrides.

Or how can I use this overrides in an new file ?

Many thank‘s for help

Kind regards
Patrick

The essence of overrides is that they are changes that are not predictable, or following a pattern. I really don’t understand how you want them to be integrated into a template. Could you elaborate or show an example of what you are trying to achieve?

I want to separate the book into different parts but with the same layout

What you can do (but that’s got nothing to do with flow headings overrides) is create page templates that look the same, with different content in them. For the time being, it’s not straightforward, you’ll probably need to build you a template outside of Dorico with all the measurements, so that you can recreate it faithfully using the Properties. Dorico can handle a lot of templates, make sure you give them recognizable names.
