Nothing dramatically better exists, as far I am aware. You could use cast_embed but that doesn’t help you much because you would still need to load the old value of the list and then update it, meaning that put_embed is the better choice here since it assumes the exact same use case.
cast_embed would be a good choice if you were receiving an entirely new list with which overwrites the old one (and usually if that new list is coming from external request).
