• I checked all open feature requests and none of them matched my request.

Context

atm using nock.back will dump the exact request to a fixture file, this resolves in saving sensitive data such as

"scope": "https://graph.facebook.com:443",
"method": "get",
"path": "/v13.0/me?fields=id,name,picture,email&access_token=some-dummy-token", <-----------------

it'd be great if we can at least manually change the fixtures to support a wildcard asterisk (*)

related to #300 which dates back to 2015

Alternatives

manually changing the fixtures...

If the feature request is accepted, would you be willing to submit a PR?
