Homepage vertical display of areas

Hi,

In the home page (area group page), I'd like to display the areas verticaly by default.

I tried to put to overview iviews in a page with a 2 columns layout but the display of areas stays vertical.

I also tried to change the positions to 1 and 3 in the assignment to area group page, no luck.

Anyone knows if there's a way to do that without touching the java app.? Maybe some parameters to add?

Thanks!
