Minor backstep. On the bright side, I remembered the general way I accomplished the last two steps. Down side, I was silly and didn’t write down specific values for attributes and a precise sequence of steps that would keep things consistent where needed. So I was able to go back an reinvent the process, but this time remembered to jot down the necessary notes and realized it would be best to do all of a type of region first, then the next, etc., than to try to sweep down from one to the next. Still a step forward, huzzah!
