Changing the "center" of the screen

The idea to expand the game over 2 monitors.

But when this is done, the center of the virtual screen, for all selected objects, falls between the monitors and the game can’t be played like this.

Is there a way to change the coordinates of the default selected object to 1/4th from the right and 3/4ths from the left, in other words exactly where it falls when only the right monitor is used, in the center of the right monitor?
