[Scribus] Printing facing pages

[Ryan Grace]

Hi All,

I'm new to Scribus, but because of it's impressive design have been able
to pick it up and run with it pretty quickly.  My first project is a
newsletter that will have letter-sized facing pages (8.5" x 11").  I want
to be able to print this out double-sided on 11" x 17" paper and fold them
together, maybe with a staple in the middle to keep the pages attached. 
Is there a way to simplify this in Scribus?  If not I'm looking at having
to predict how many pages I will have first, then arrange the contents so
everything prints correctly when the content is filled in.

Thanks,

Ryan
