LyX ⇒ How to put something after preamble but before document begins ?

[n49o7]

I am trying to use the following bit of code

Code: Select all

\DefineBibliographyExtras{french}{\restorecommand\mkbibnamefamily}

but it has to be inserted after Biblatex loads (after \makeatletter) but before \begin{document}.
Is there a way to do that or to somehow pass the option through the (sexy new) bibliography tab in the document settings ?

You can delay stuff in the preamble by enclosing it in \AtBeginDocument{}.

If that is what you really need, I cannot say, because you gave no MWE to test it with.
