That's how I did it. Of course, I am no expert, and have done this exactly once, but I did include the cyl and axis unchanged and the results seem to be perfect. Thinking about ordering another pair so I can just leave one at work, I'm so pleased.
It is a little disconcerting, however (after years of one pair of progressives or bifocals for everything), when someone walks into my office and I look up and can't see them! And I still get up from the computer and start walking away wearing the wrong glasses.
