Accept subset of Ash.Type.Enum in action

I have an

Ash.Type.Enum

Ash.Type.Enum

Ash.Type.Enum

Ash.Type.Enum defined as

defmodule Dreng.Accounts.Role do
  use Ash.Type.Enum, values: [:superadmin, :admin, :farmer, :farmhand]
end

defmodule Dreng.Accounts.Role do
  use Ash.Type.Enum, values: [:superadmin, :admin, :farmer, :farmhand]
end

defmodule Dreng.Accounts.Role do
  use Ash.Type.Enum, values: [:superadmin, :admin, :farmer, :farmhand]
end

defmodule Dreng.Accounts.Role do
  use Ash.Type.Enum, values: [:superadmin, :admin, :farmer, :farmhand]
end

And the

User

User

User

User resource is using it with

    attribute :role, Dreng.Accounts.Role do
      allow_nil? false
    end

    attribute :role, Dreng.Accounts.Role do
      allow_nil? false
    end

    attribute :role, Dreng.Accounts.Role do
      allow_nil? false
    end

    attribute :role, Dreng.Accounts.Role do
      allow_nil? false
    end

In my create action I'd like to accept a role argument, but only

:farmer

:farmer

:farmer

:farmer or

:farmhand

:farmhand

:farmhand

:farmhand should be allowed, and ideally I'd like to keep all the benefits of using

Ash.Type.Enum

Ash.Type.Enum

Ash.Type.Enum

Ash.Type.Enum like automatic casting. What would be the idiomatic way of accomplishing this?
