Independent Left-Right Column Layout? - 2007

[Foppa]

I'm creating a landscape document that I'll need to fold like a book once printed.

I've set the "Page Layout" columns to two, but how can I make these two columns independent from each other?

When setting the columns to two, I have to hit enter until the cursor jumps to the right column. Also, when deleting a line or hitting enter on the left-side column, it effects the right-side by shifting things around.

Is there a way to make them separate from each other?
