Changing starting point on 2D job

I'm using LinuxCNC as part of a wire EDM, and it's also my first experience with Linux of any sort.

When I load a job, a 2D representation appears on the Preview tab and on the figure is an "X", where cutting will start. Depending upon the shape of the blank and the outline of the part, it's sometimes better to have the starting point elsewhere. Is this something that can be changed within LinuxCNC, or can it only be done in the program that generated the G-code file (Vcarve, in my case)?

Thanks

Not what you asked, but try Inkscape, it is free and it exports ready for use gcode, and more importantly very easy to use and add a line for were you want the cut to start.
Vcarve is really, really not for EDM, as far as i am concerned.

Huh, shows what I know - I'll certainly check out Inkscape!

To be clear, I use Alibre for CAD and borrow Vcarve's vectoring feature to convert it to G-code with my own post-processor.
