Call menu during messages

My VN uses a custom menu that runs off of a common event, so..
How would I use this plugin to instead of calling the menu, call a common event?

 

@KeitaNeko Why do you need this plugin if you using custom menu? Unless you are using some standard scenes too, like save-load scene, then you can use it to fix some bugs(for than you need only to install the plugin). In other cases there is no point and you can call your menu by common event without this plugin.
