Cat 930K second screen

Now that we have added the snow blade and started to pop hoses! It on a Cat 930K vin CAT0930KTRHN01765 According to the operational manual says to 3rd function can be adjusted with the second screen or with a laptop? Can the second screen be added? depending on cost? Or should I look into what is needed to use a laptop? What is involved in using the Cat software? As the fleet is growing and may be a necessary item! Thanks in advance for any advice! Mike
