Xplane .obj headers

[domhenry]

Still trying to get a full header at the top of an export object file.
My typical is:

GLOBAL_cockpit_lit
TEXTURE aircraft.png
TEXTURE_LIT aircraft_LIT.png
TEXTURE_NORMAL aircraft_NML.png
GLOBAL_specular 1.0
NORMAL_METALNESS

I've used the markup in the plugin option with:
GLOBAL_cockpit_lit\nTEXTURE_NORMAL %b_NML.png\nGLOBAL_specular 1.0\n

That gives me:

GLOBAL_cockpit_lit
TEXTURE_NORMAL aircraft_NML.png
GLOBALspeccular 1.0
TEXTURE aircraft.png
TEXTURE_LIT aircraft_LIT.png
NORMAL_METALNESS

Is there any way to turn off the last 3 lines so I can add the full markup myself...
