Carving from the centre of a piece

dear all I would like to carve a perfect circle out of an irregular, piece of wood, as such I would like my home position to be
in the middle of the wood, is it possible to have a home position on the middle instead of the bottom left corner?

Work zero (or Home Position as Easel calls it) can be set to anywhere the machine can reach.
To set work zero to the middle of a piece of material, the center of the design to be carved must be centered over Easel X0Y0 grid.
