Disabling Tool Macro at Beginning of GCode File?

Hi,

I’m very beginner with KM and I’d like to be able to not include the Tool macro at beginning (only) of all my exported gcode files. I cannot empty this section as obviously I would need it for a real tool change. May be a little odd but I prefer managing this as job preparation steps, ie out of the gcode file. I searched to achieve this without success. For now I had to edit each gcode file manually to remove it. Is it possible to disable this ?

Thanks.
