Not sure if I understand completely, but you might try setting the following in the config file:
PHP Code:
define('SPIDER_MAX_LIMIT',1); //max recurse levels in sipder - default = 20
define('SPIDER_DEFAULT_LIMIT',1); //default value - default = 3
define('RESPIDER_LIMIT',1); //recurse limit for update - default = 4
so that the number of levels crawled is one.
