LyX reverses the order of geometry and fancyhdr packages

Greetings,

I am trying to produce the following header structure:

-------------- next part --------------

-------------- next part --------------



This is easy to do in LaTeX:

\documentclass{article}
\usepackage{geometry}
\usepackage{fancyhdr}
\pagestyle{fancy}

\begin{document}

\lhead{left}
\chead{center}
\rhead{right}

Some text some text some text some text some text some text some text some text some text some text some text some text some text some text some text some text some text some text some

\end{document}


When I try to type the same document in LyX, however, the output comes out incorrect.

Notice how the header dimensions are different than the text dimensions. The reason appears to be that LyX insists on loading the geometry package, which changes the default margins, after fancyhdr. The same thing happens when I import the above tex file into LyX---the order of the packages is reversed and geometry is loaded last, resulting in the incorrect output as in the second picture.

Is there a way to make LyX respect the correct order of loading packages or some workaround to produce the correct output as in the first picture?

Best,
