There is no built-in option for that. But it is possible by adding some custom code. Add the following code to your theme’s functions.php file. Replace the term1, term2 with the category term of your choice. You can add more.
function wpdm_set_default_package_category( $post_id ) {
$current_post = get_post( $post_id );
// This makes sure the taxonomy is only set when a new post is created
if ( $current_post->post_date == $current_post->post_modified ) {
wp_set_object_terms( $post_id, array('term1','term2'), 'wpdmcategory', true );
}
}
add_action( 'save_post_wpdmpro', 'wpdm_set_default_package_category' );
