That link doesn't seem to work for me, it comes up as "forbidden".
But, I think I understand what you're getting at. I think at one point I looked at multi-dimensional arrays, but there was an issue using them with the LCD so I stopped exploring it. But, I think the issue was people trying to use them to bypass the LCD 8 custom character limit, and not what you're saying. I'll give it a try. Hoping I'll have the hardware set-up ready to go in a week or so, then I can actually give it all a try and confirm it works. Thanks!
