if you watch the video it is explained why doing it that way is beneficial (cross platform compatability)
if you want to make it match your input actions/axis by name, you’ll just have to manually enter the same names in the data table. Or you could otherwise roll your own system in which you associate an input action with a name, and pass the name to widgets, but that would be a butt-load of work to get a less robust system that you’d get with commonUI.
