Ash Graphql "create" mutation with upsert? true – how to use ID as argument for upsert identity?

I have a Graphql create mutation within which upsert? true and upsert_identity :id. I have an action corresponding to this (code below). Can I get id to be an acceptable input to this mutation? Thanks! 
    mutations do
      create :upsert_patient, :upsert_patient, upsert?: true, upsert_identity: :id
    end
    mutations do
      create :upsert_patient, :upsert_patient, upsert?: true, upsert_identity: :id
    end
    create :upsert_patient do
      upsert? true
      upsert_identity :id
    end
    create :upsert_patient do
      upsert? true
      upsert_identity :id
    end

And to clarify – if the id is provided and does not match an existing record – I want that to result in an error. If the id is not provided at all, I want that to result in a "create". And if the id is provided and does match an existing record, I want that to result in an "update". What's the recommended way of going about doing this? I initially had two separate mutations for two separate actions (create and update) but when I saw upsert? true was an option – I wanted to take advantage of it.

🤔 I think you need to do something a bit custom for that 
create :upsert_if_id_not_specified do
  argument :id, :uuid

  manual fn changeset, _ -> 
    case Ash.Changeset.fetch_argument(changeset, :id) do
      {:ok, id} ->
         lookup_and_update()
      :error ->
        call_upsert_action()
    end
  end
end
create :upsert_if_id_not_specified do
  argument :id, :uuid

  manual fn changeset, _ -> 
    case Ash.Changeset.fetch_argument(changeset, :id) do
      {:ok, id} ->
         lookup_and_update()
      :error ->
        call_upsert_action()
    end
  end
end
