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.

wp-author-import-auto-select.js

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

		$(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);
