Is there a way to programatically set the default font?

 

If a user prefers a default font (e.g. we have a dropdown with fonts on a "front page"), can I somehow pass on that font to the editor to use as a default?

 

Will I have to somehow programatically change the textarea values in the stylesheet file?  Or will I have to have several stylesheets (with different fonts specified in each stylesheet for the textarea) and change the stylesheet that the EditorWysiwygModeCSS property points to?  Any other options?  Thanks
