Mega 2560 adding XMEM+ Memory

Is there an easy way to reconfigure parameters in the Arduino IDE so that you can compile sketches directed towards a Mega 2560 board that has an added Memory expansion shield added that is supposed to expand the original 8192 bytes of SRAM by another 32k. I've been told it is not easy to reconfigure and I should be using Atmel Studio to compile the sketch.
