删除“添加新功能”，同时保留对自定义角色类型的编辑功能

Question

我试图限制来自低于编辑器的任何人的自定义类型类型（“居民”）的“添加新”功能。但是，我希望我的自定义角色（也称为“居民”）能够编辑现有（和将来）的CPT

我不接受这个建议：https://stackoverflow.com/a/3248103/3239470确实确实有效，但是它为所有人（包括我仍然需要的管理员/编辑）消除了“添加新内容”的需求。

我尝试为管理员/编辑者重新添加create_posts / create_residents功能，但它似乎并没有采用，也不会覆盖已注册的CPT中设置的功能。

我也正在多站点设置中执行此操作，这对您有所帮助。

我不希望通过CSS删除它，但是实际上应该禁用直接链接，如果有人键入URL，但是我开始认为那是我唯一的选择？任何方向或建议，不胜感激。
