根据条件添加管理菜单或子菜单

我在两个不同的文件中有两个插件，它们在管理面板中添加了一个子菜单（插件标题），如下所示：

插件1：

function myplugin1_setup_submenu(){
    add_submenu_page("mybrand", "My Plugin1", "My Plugin1", 0, "myplugin1", "myPlugin1PageFunction");
}
add_action(\'admin_menu\', \'myplugin1_setup_submenu\');

插件2：

function myplugin2_setup_submenu(){
    add_submenu_page("mybrand", "My Plugin2", "My Plugin2", 0, "myplugin2", "myPlugin2PageFunction");
}
add_action(\'admin_menu\', \'myplugin2_setup_submenu\');

必须在某个地方有一个菜单，它是这两个插件的品牌：

function mybrand_setup_menu(){
    add_menu_page( \'My Brand\', \'My Brand\', \'manage_options\', \'mybrand\', \'myBrandPageFunction\' );
}
add_action(\'admin_menu\', \'mybrand_setup_menu\');

但这不符合我的需要，因为我需要做的是：

如果该品牌安装了一个插件，我希望该插件是管理面板上的一个菜单（而不是子菜单），在这种情况下，我不希望该品牌出现在任何地方。

但是如果这个品牌安装了多个插件，我希望它们都是“我的品牌”菜单的子菜单。

我怎样才能做到这一点？

非常感谢。
