New Scanner Arrived

The BCD996XT arrived today and is ready for uploading, usb drivers are installed and everything seems to be ready. I'll be using Freescan to load everything, I watched the 2 videos on the freescan user guide page and I believe I shouldn't have any problems. Although I do have a few questions, when making a system as in the video, he gave each system, conventional and trunking the same quick key number. I'm assuming that I would have a different quick key number for every system created. The other question was, after creating a couple of systems and saving that file and later I want to add more systems, I would want to open that file and add the newly created systems to that file. I hope I'm making some sense here, my apologies for these redundant type questions. Thanks for help as well!
