ListView item anchored?

Hi,
Is there a way to have the ListView item positions adjust depending on the form size, or portrait/landscape presentation?
I have a ListView with all my items set correctly using the "Toggle Design Mode" option. But how to tell each item to stick to the right or left of the list when the view width increases?
I have columns with totals, but they remain in the same position when flipping to landscape mode on mobile devices?

In Portrait they're on the right of the screen, in Landscape, they stay in the middle of the screen instead of moving to the right.

Thanks for any clue.

Steve
