Horizontal alignment of item lists

[MidFidelity]

Hi!
Is there a way to change the horizontal alignment of the item and favorite list?
If I limit the number of columns for these lists they are aligned to the edge of the screen with a gap between the Inventory and the item list.
Is it possible to change this alignment so that I have i.e. 5 columns of items to the right of my inventory and then a gap to the edge of the screen?
NEI has that option called called HorizontalAlignment in the config but I cannot find it in REI.
