Scott,
Yes you can stored 'single' registrations setups into one of the 198 memory slots of a 'block' registration. And also export a registration located in one of the 'Block' registration's 198 memory slots and save it as a 'single' registration easily.
Once you pressed Block Registration once, the button LED stays lit and you can switch from one reg. to another reg. by just pressing 1 to 3 numbers. Press 4 for #4, not 004. Press 26, not 026...
When 10 titles are displayed on screen, you scroll to the title you want and then press 'LOAD'. I prefer using numbers, it's much faster.
