I've never done that, but it seems like what you'd want would be something like:
PHP Code:
$actiontemplates['editoptions']=array_merge($actiontemplates['editoptions'], array('awc_ucp'));
or maybe just
PHP Code:
$actiontemplates['editoptions'][] = 'awc_ucp';
You didn't say what you meant by "didn't work", so it could also be something to do with the plugin you're using.
