I'm still relatively new, so I trust someone will correct and instruct me if this already exists. I have looked and have not been able to find it.
It would be nice if there was an option to return the standard 2 letter abbreviations for states from the Allocate Input tool's "Pick Variables" "geographic Identifiers." Currently, the only identifiers available are "Key" an"Name":
Where, Key is numeric ("02", "44", etc.), and Name is the full state Name. In order to join to most of our databases, I usually need this to be the standard 2 letter abbreviation. This forces me to join to another database table to translate it.
