Hello Paolo,
Please note that default values are intended to be changed if required.
Hello Valentin,
as said before I don't want this kind of customization: I think it reduces readability of the code (unless it is wrapped, but this would be not practical) and it is not easy to maintain.
I just want to set simple fields, without any logic, without any coupling, cross-link and/or low level functions. This is what I do with LibreOffice (GUI) or with predefined templates (LaTex, WordPress etc.). I really don't know how to explain this better: please, refer to Jean's last post. It will help to understand how to focus the problem.
Best,
P
