change DXF sketch line to yellow using macro

I will start this off by saying I have only on the Job training with solidworks. We create sheetmetal parts and have been using this macro to create cut patterns  

 

I would like to edit it to have the ability to change the sketch lines to yellow as this is how our laser tells the difference between cut and etch lines. we currently map this manually but would like the ability to add it to the macro. I'm not sure if this is possible or not, or if anyone else has experience with this.

any feedback would be appreciated.
