Is there a way to use manage_relationship to manage all existing records

Hi, I have a Resource called Team which has a TeamMember relationship :members.

Is there a way to use change manage_relationship(...) and apply an update action to all members?

E.g.

# Team.ex
update :activate_all_members do
     change manage_relationship(:members, ..., type: :update, action: activate)
end

The only alternative I can see right now is to implement a manual action, but is that really needed?

Definitely no need to do write a manual action. You can do everything you want with a change and a hook

defmodule ActivateAllMembers do
  use Ash.Resource.Change

  require Ash.Query

  def change(changeset, _, _) do
     Ash.Changeset.after_action(changeset, fn changeset, result -> 
       Member
       |> Ash.Query.filter(team_id == ^result.id)
       |> Ash.bulk_update!(:activate, %{})

       {:ok, result}
     end)
  end
  
  def atomic(changeset, opts, context), do: {:ok, change(changeset, opts, context)}
end

update :activate_all_members do
  change ActiveAllMembers
end
