I am trying to find a way to autonumber a select set of polygons that are in a grid (somewhat) format. These are actually PLSS 40's so they aren't exactly a grid. I want to avoid entering these manually so I wanted to see if anyone has been successful in completing a task like this? I tried using lat/long but was unable to make it work. Attached is a screengrab of what I want to accomplish (these were entered manually).
