You can add TGs by manually programming them. The keys 0 to 9 are for banks only. TGs are controlled by sub-groups and/or locking them out individually. When you are adding alpha tags it is a lot easier to use software to program the scanner. You'd need to read data from the scanner, modify it, and rewrite it all back to the scanner. I use WIN97. But to answer your question, you can add them manually one by one as you desire.
