Attributes with function name

Can you use custom attributes similar to @impl or @behaviour, but rather than using a callback function, only the function name is used (e.g. @description Mod.fun).

# A.ex
defmodule A do
  use C

  @description1 "function11 returns :ok"
  def function1(_a) do
    :ok
  end

  @description2 A.function1
  def function2(_b) do
    :ok
  end
end

In the example above, the @description1 attribute is valid, since what follows is a string. Then, in @description2 fails since it tries to get a value, but instead I wish to get the name of the method (i.e. A.function1).

defmodule B do
  @behaviour Bar
  @callback foo
end

Some elixir modules are able to do something similar. For example, you can set modules/methods to @behaviour and @callback. Can something similar be created?
Thanks.
