Just received CX-PB001 yesterday so no expert but according to User's Manual in Expert Menu you can
Model Save -- Save parameters in CX-PB001 as a model
Model rename ---Rename a model that you save in CX-PB001
Fact is from what I can see the programmers does everything the computer software does. I do agree that the computer GUI is easier to use but sometime you do not need a sledge hammer to drive a thumb tack.
