Can you change document properties with JS?

Hi all,

I have a script for adding layers that works perfectly. However, after executing this script I want to change the document properties to "fit page" and "show layers panel". Is there a way to set the navigation tab, page layout, and magnification using a script (under File>Properties>Initial View)? I know you can set those as your default in acrobat, but this script will be used by others who may not have that as their default, hence why I want to include it in my script.

Thanks
