Sorry, I should have been clearer with my question.
The macro has one input and inside the macro, the node that defines or exports the input needs to look up the input node's controls.
The input node exists outside the macro, so you can't hardcode it inside the macro and if you do, it won't be automatically updated when you connect the input node to the macro in your composite.
