you can change the location of the icons to the left, if the centered layout is what you mean
With multiple monitors, it snaps to the side most one you have plugged in regardless of your primary screen.
I get there's a lot of dragging and dropping involved with the bar, but in Unity it let you set a threshold for mouse speed to limit you going to another monitor.
Just let me put it on the side and do that if I'm dragging something, it's not too difficult.
