When a totally new system is put into place, often we don't all know the TGs. Heck we might not know ANY! What you can do is program only the wildcard and let 'er scan. As each TG ID comes up, Store it. If it's something you don't want to monitor, store it and lock it out. As they get identified you can add alpha tags. If it's a small system you can continue this way. If it's a large system, it takes a lot of memory just to hold the locked-out TGs. How to handle is up to you.
