question on finding ARCH standard sheet format in SW2010? not available as an option

Hi All,

I'm trying to find the Architectural standard sheet format in Solidworks 2010 and only see ANSI available choices for various sizes.  We normally deal in the 24 x 36 Arch format with inches (I think this is ARCH C?) at work and not the metric sizes / ANSI.  I'd like to know where to find this option to load in for making a drawing.  Do I have to download this size from somewhere thru design library?  As you can tell, I'm still learning SW.  I'd appreciated any help!  Thanks in advance.
