Change "Continue Reading" Text

Yes. Below is an example of how you would display the blog post title instead of the ‘continue reading’ link:

add_filter( 'mpress_custom_feed_excerpts_continue_reading_link', 'custom_feed_excerpt_link' );

function custom_feed_excerpt_link() {
	global $post;
	$post_title = get_the_title( $post );
	$permalink = get_permalink( $post );
	$link = '<a href="'. $permalink .'">'. $post_title .'</a>';
	return $link;
}

You can place that code in your active theme’s functions.php file.
