In Creality Workshop, I have an image that I can print, however, I manually have to set the laser head to the proper position before I can begin engraving.  

I want to automate that with a starting gcode.  I have successfully created and run my starting gcode script.  However, if I try to put it on the beginning of the Gcode generated by Creality Workshop using the “Load Gcode Head” button, nothing gets added to the front of the Gcode when I use the “Export Gcode” button.

If I manually edit the gcode and copy and paste my starting Gcode lines, the operation proceeds successfully.

How can I set this up so that I can have a Gcode Head prepended on the exported Gcode file?
