Hammer hostgroup edit/add/change smart class overrides

Unable to figure out how to change smartclass overrides with hammer.

Is it possible to change/add/manipulate smart class parameters from hammer? Id like to create a hostgroup and set overrides for a class, im not sure how to do that from hammer or see a way to do it.

Well I should of looked a few more minutes. Funny that the problem kind of answers itself after posting the question…

It looks like you have to add matchers to the smart class its self for the hostgroup. That can be done with hammer sc-param add-matcher

Mind posting a real world example of this command? New to hammer.
