Auto-select authors for posts during WordPress import. They must already be assigned to the project. Enable jQuery in a plugin or functions.php, and paste this in the browser console.

(function($){
$('#authors li').each(function(key, value) {
	var name = $(this).children('strong').first().html();
	var re = /\s\([^\)]+\)/gi;	
	name = name.replace(re, '');
	name = name.replace(':', '');
	name = name.replace("'", "");
	name = name.replace(".", "");
	name = name.replace("&", "");

	$(this).find('select').first().children('option').each(function(){
		if (-1 !== $(this).html().indexOf(`(${name})`)) {
			console.log('Comparing ' + $(this).html() + ' to ' + name + ".\n");
			$(this).attr('selected', 'selected');
		}
	});
});
})(jQuery);
