Place formatting codes - adding/changing code and place type

Recent discussion of the new report ‘‘Ancestral Lines Expanded’’ caused me to revisit the display formatting capabilities of the descendant report group. In particular, default place formatting codes have a distinctly US flavour e.g. city and state, whilst for the UK, town and parish would be more relevant. Has anyone changed the default formatting code/place type relationships for these descendant reports and, if so, how was it achieved?
