centering a whole note/chord

[Federico Bruni]

I have a simple question, but I could not find any solution around.
I'd like to move a whole note a bit on the right (or put it in the
center of the bar).

In the following example I'd like to move to the right or center the
chord in the last bar.
Any hint?
Thanks!
