Suggestion for Cox - Text size

I understand that you can change the text size going to the Settings of your receiver. However there are only two choices of medium and large.

Large isn't big enough when watching on a smaller tv or even when watching a larger tv from a distance. It's hard to read. I would imagine that elderly people would really struggle with this.

A suggestion is to add even larger text sizes as alternatives. Or perhaps even a button on the remote that you can push and instantaneously adjust the text size much like you can do on your laptop screen when you push Control and the + tabs.
