This might be very specific to my gym, which is Pure gym in Rochdale, 10+years old so perhaps out of date. But there is a wide cable crossover machine, the one with seated rows, lat pull downs, tri cables incorporated at each end, but this is always quite busy so the alternative is the smaller Matrix crossover machines, but due to different sizes, lever arms to weights etc, you can't do the same weight for the same exercise on each machine. So it would be good to be able to leave your own notes on specific sets to act as a reminder when you do the exercise the week after on the different machine. This applies to a lot of the equipment and would also be helpful if hopping between different gyms due to work for example.
