318675 button aligning

Our client want all the buttons for the shop to have same exact vertical aligning if one button on the page its aligned right on one particular spot 2 buttons is one aligned centered, one same as above (exact same spot page wise, of course i understand that if a buttons is on top, it will stay on top) if 3 buttons , one is aligned left, etc. So if you click in the pages and take a pencil, hold it vertical on the page next to a button, and click other pages, button is same aligning
