I have two super view controllers `MasterCategoryListViewController` and `MasterCategoryItemViewController`. 

I want to use these in several apps.

I inherit from both of these

```
class CustomListController: MasterCategoryListViewController
class CustomItemController: MasterCategoryItemViewController

```

Now in the `MasterCategoryListViewController`

I have a button handler...

```
@objc open func btnAddTapped(sender: UIBarButtonItem) {
    let itemViewController = MasterCategoryItemViewController()
    itemViewController.title = "Type"
    self.navigationController?.pushViewController(itemViewController, animated: true)
}

```

I know I can override the method to push to `CustomItemController` however, I'm just wondering if I can do this in my `MasterCategoryListViewController`, obviously without it knowing anything about what `CustomItemController`?
