Geo Library Shapes using 3 digit zip/postal code
The Geo Shapes mapping feature is very useful and has a good deal of ways to define the shapes based on State, zip/postal code, etc. A noticeable downside is increased lag as the layers become more granular. This is especially problematic when creating large shapes based on full zip/postal code.
A great addition to the Geo Library Shapes would be the ability to create layers based on 3 digit zip/postal code (e.g. 928**). This provides a good level of granularity and reduces the complexity when creating larger shapes layers (e.g. Sales Territories/Regions).

I think they're technically called SCF (Sectional Center Facility).

This would be killer. This is exactly how we've done territories for years.
