How to include custom post type title in BuddyPress activity feed

I am using custom post types that I will be displaying within my BuddyPress activity feed. I am able to setup the post types to work within the feed just fine, but I am unable to find documentation about how to display the title within the feed. Here is my code, I want to display the post title where [title] is:

add_post_type_support( 'news', 'buddypress-activity' );

function customize_page_tracking_args() {
    // Check if the Activity component is active before using it.
    if ( ! bp_is_active( 'activity' ) ) {
        return;
    }

    bp_activity_set_post_type_tracking_args( 'news', array(
        'component_id'             => buddypress()->blogs->id,
        'action_id'                => 'new_news_item',
        'bp_activity_admin_filter' => __( 'News', 'custom-domain' ),
        'bp_activity_front_filter' => __( 'Pages', 'custom-domain' ),
        'contexts'                 => array( 'activity', 'member' ),
        'activity_comment'         => true,
        'bp_activity_new_post'     => __( '%1$s - <a href="%2$s">News: [title]</a>', 'custom-textdomain' ),
        'bp_activity_new_post_ms'  => __( '%1$s - <a href="%2$s">News: [title]</a>, on the site %3$s', 'custom-textdomain' ),
        'position'                 => 100,
    ) );
}
add_action( 'bp_init', 'customize_page_tracking_args' );

Within this line of code I can see that %1$s is the user name and %2$s is the post link. Are there more of these snippets within BuddyPress that I can use, specifically one for the post title?

'bp_activity_new_post'     => __( '%1$s - <a href="%2$s">News: [title]</a>', 'custom-textdomain' ),

Thanks for the help!
