This may or may not help you - but I see that you are a subscriber, so you might consider downloading FS and just experimenting with local conventional and trunked systems and seeing what happens. Check out how the software is organizing things and how the radio receives. Check out how things like quick keys will work for you to turn on and off the things you want to scan. Get a practical feel for how systems differ from sites and channels. DON'T spend a whole lot of time making the alpha tags pretty or readable or doing other time-consuming setup work until you've had a chance to fiddle around and see how things work and what will work for YOU and your systems of interest. One of the great things about using the software is that you can keep copying, deleting, etc. until you're happy - but do the "mock up" and trial runs first. I hope that helps. For me, reading a manual only goes so far. YMMV.
