Dynamically change styles and CSS sheets

Hi there !

I am using FCKEditor, and instead of reloading the editor each time, I would like to update it dynamically.
What I can do for now is to change the text, but this is easy.

What I would like to do is to change the style and css sheets dynamically (StylesXmlPath and EditorAreaCSS).

I could not find a method to do it. Is it possible ?

Thank you a lot,
