field calculator - Giving polygons classificaton code in ArcGIS Desktop?



Does anyone have a trick for assigning polygons a code based on the classification classes?


For example, if I symbolize the population of census blocks with 10 classes using Natural Breaks, I would then like to add a new field to the table where each polygon will assigned a number 1 through 10 that represents the natural break class the polygon fall in. Similar to Reclassify in Spatial Analyst but using a polygon instead of a raster.
