Can't set custom FloatingActionsMenu

I want to create my own FloatingActionsMenu, but there's no way to set it to recycler view. The only method is setDefaultFloatingActionButton, but it is for one button. This method is commented out in library code:

//    public void setCustomFloatingActionView(View customFloatingActionView) {
//        this.floatingActionMenu = floatingActionMenu;
//    }

Maybe you should add a public method to set mFloatingButtonView or mFloatingButtonViewStub?
