For my project, I need to mock responses from an API where some of the parameters are included in a HTTP header, so for example I would make a request to http://api.com/projects with a http header set to user-id: joebloggs

Currently I am recording the responses by doing:

@_recorder.record(filepath="out.yaml")
def test_something():
    ...

and then I'm loading the yaml file like this:

@responses.activate
def test_something():
    responses.add_from_file("out.yaml")
    ...

Is it possible to set up the registry to match on this HTTP header, and also save this header in the .yaml files that it generates?
