Changing material center

is there a way to change the X,Y starting/centering point?
now i have to set the starting point in the left bottom corner.
in order to make a 2 sided project, without drilling, i want to use both sides centers as starting points.

Yes, you place the center of your design on the Easel XY0 grid point.
Easel always assume work zero is at the XY0 Grid point.
