字典中的列表元素按照某个字段的优先级列表排序

dic字典中每个key对应的一个大字典，这些大字典的结构完全一样，里面有一个channel_settings列表，这个列表中包含结构一样的小字典，这些小字典有一个channel_settting_id字段，现在的需求是，我有一个外部的channel_setting_id_list列表，我想根据外部的channel_setting_id_list列表的顺序，对每个大字典的channel_setting列表中的元素排序！

代码：

from pprint import pprint

dic = {
    "A": {
        "name": "这是模版名称（测试wbx）",
        "message_template_group_id": "7391503245786869761",
