We have added the ability to organize Northing/Easting Points into numerical Series ranges, along with the ability to renumber points.
We have some more enhancements planned. Although currently no plans to organize the notes by a character suffix like you show. Having numbers 3T, 3W, and 3S would not allow easy renumbering of points. This is why we kept it strictly numeric, as we felt renumbering notes was more important than using a character.
But we do plan on adding a Title to each numeric Series, so that should help.
