Im a little confused, although i havent tried this yet. I understand your first example for adding an additional register and display the same pattern on both sets of LED. For adding an additional pattern i cant see where the pattern names have been added or called by the code. In your second example the code is exactly the same as the additions for the first and i don't know how to name or call the second pattern. Could you help me out with an explanation of how to name that second pattern and where and how to differentiate between the two patterns in the code. Please don't get me wrong, if it work ill be chuffed to bits but it would also be nice to know why and how it actually works as i will be using this same process quite a lot over the course of the next year or so. 
Thank you
