default style for new rich text?

Hello all. Would there be a way to have DT produce new rich text files not only with the typeface and size set in preferences, but with specified settings concerning e.g. column width, indent, line spacing, justification and the like? Thanks a lot in advance.

You could create a document using these settings and export it as a template (File > Export > as Template…). Afterwards it’s available via Data > New From Template > …

yes, I should have seen that. Sorry, and thanks.
