Ajax form output filtering

Hello,

This plugin is a feature I was just about to create, and then fumbled upon your implementation. It’s working great!

However, if I may suggest to add a filter to modify the ajax form output would be great, something like this:

foreach ( $posts as $post ) {
	$output = sprintf(
		'<option value="%1$s">%2$s (%1$s)</option>',
		esc_attr( $post->ID ),
		esc_attr( $post->post_title ),
	);
	$output = apply_filters('cp_exporter_ajax_form_output', $output, $post);
	echo $output;
}
