I don’t know if I quiet understand your question, but you can put as many functions as you please inside the quote do block in using.

For instance:

defmodule Using do
  defmacro __using__(_opts) do
    quote do
      def a(), do: :a

      def b(), do: :b
    end
  end
end

defmodule Foo do
  use Using
end

And then

 $iex -S mix
iex(1)> Foo.a
:a
iex(2)> Foo.b
:b
