Cable or Pulley Systems for Titan X-3 Flat Foot

I just set up my titan X-3 flat foot and think it’s great so far. The build quality is solid and the footing is very sturdy. No movement at all when I am using the rack. I was curious if anyone has added a pulley system of any kind to their x-3 flat foot and whether they like it. Mostly, I am looking to add a pulley/cable system for some back pulldown and tricep exercises. Let me know if you have had any solid experiences with any cable/pulley systems that work with the x-3!
