Or you could use my programmer software that will save (one time operation) and automatically reinsert the calibration stuff for you each time you program a JW part. You only then need to label each part A, B, C etc and either use them in sequence or simply select the matching "virtual" device depending on which software driver you are using. BTW Was is "PITA"?
