Assuming that your G54 zero is the lower left hand corner of the bed simple set your X and Y offsets, in say G55, to X(length of bed)/ 2 and Y(length of bed)/2. If your home is someplace else then change the signs appropriately.
Also in the .ini file there should be, or you can add HOME_OFFSET or something close to that with the appropriate numbers. Your mill should home to the switches then move rapidly to the home offset position in X and Y. I'm assuming you are happy with your Z zero. If this doesn't make sense then consult the EMC user manual or the EMC integrator manual for greater detail.
