When on a POTA activation, there are times when I work a station whose home QTH is OH but they are actually operating in PA. Would it be possible after entering the RST to give the option to enter the state. If left blank, the home state would default to the log. Otherwise, it becomes necessary to edit the state in the log.
Settings | Expanded Mode should allow you to see the State field on the main panel so you can change it without editing the QSO later.
