Our branded theme displays single choice and multi choice responses in large clickable blocks - this is ideal for the vast majority of surveys/questions. However occasionally (e.g. with a long response list) it would be better to revert to the standard radio button / check box style display. Is it possible to override the theme default without having to revert to a different (and non-branded) theme?

Unfortunately, themes can't be changed by block. Though you could adjust styling to handle this, it is going to be highly theme dependent.
