This feature has been on LOGic for a long time. Look in Help under Advanced Features/Customizing Copy from Previous QSOs, or just search.
And in the printed manual, in Chapter 4 under Logging a QSO, it is mentioned in the first section (as well as the associated section in Help):
Quote:Click the Add New QSO button. Type a call in the Call field, then press {Tab}. The little box to the
right of the call field will be checked if the station has ever been worked before. If the station has been
worked before, name, QTH and state will be copied from previous QSOs.
