What you are looking for is the chain cutting function in your Cam nesting software. I am not overly familiar with the EZ-Gcode software that you are using....so I sent an email to a friend of mine that happens to work for MultiCam....I am sure he will get back to me soon.
Hypertherm has CAM software that can easily do what you need to do...and more....however lets see if what you have will improve your process as well.
Here is a link to the MTC software that is offered by Hypertherm....we closely link the CAM software to the other Hypertherm components in the system....and MultiCam works with this software as well.
