It is occasionally needed to explicitly call a config mode script based on the settings within a given config mode script; an example: on setting a firewall group, the conf_mode script nat.py needs to be manually called if there were no changes properly under the path 'nat' to trigger an update. This task will cover the general solution, listed as difficulty level 'hard', although a rough design is clear. Sub-tasks will address the specific example mentioned, and similar cases, listed as 'bug'.
