Sure, just click on the playlist tab at the bottom of the iscan program screen, chose what playlist you want to add the frequencies to from the pull down menu in the upper left hand corner, then click the "new channel" button on the upper right of the screen. This will open a add new channel wizard that will take you through the process. Not quite as easy as just typing into a spreadsheet but maybe a new program update will have some new features. Be sure that what frequencies are on the iscan program playlist are the same as what is on the sd card/scanner since when you add to the iscan program and write to the scanner, it will over write anything that is not the same. I just keep the computer program freq list as my "master" and sometimes add things temporarily to the scanner playlist manually, knowing that the next time I update my sd card all will be brought back to base one. Hope this helps! Have you visited the wiki section pertaining to the Pro 107 yet - great information.
