If I understand you right, you wish to start a new cam job with the first fitting having a certain fitting number. If that is so, you can change any item number you wish. For example, if you want to start at fitting number 97, just change the first fitting entered from #1 to #97 and the fitting ID #'s will continue from there. This only works with numbers, not so well if you have a letter mixed in with your fitting number.
