[Koha] borrower state

We have patrons (borrowers) from many states and countries. Is it possible to separate the city and the state anywhere? We also keep track of the in-state patrons home counties. Zip codes don't really work since some go across county lines. Any suggestions? -- Linda Culberson lculber@mdah.state.ms.us Archives and Records Services Division Ms. Dept. of Archives & History P.
