Want to add drilling capability to my cnc plasma

Does anyone have any idea on how I would go about doing this? I'm imagining I can take off my torch mount, mount a drill, or low speed spindle, and somehow use sheetcam and Mach 3 to run a drilling operation, I drill thousands of holes each year in aluminum 2x2 tubing, and if I could automate it, that would be amazing.

Also does anyone know if I would need a custom post processor?

Thanks
