How do I use something similar to --proxy-all but in wiremock cloud?

It could be done via the recording mode for a short test. Not sure we expose this otherwise, it does not seem to be documented at least. CC @Tom @Rob Elliot

Hi @Iu Dragon all that

--proxy-all

does is create a single stub matching any method, any URL with response that proxies to the specified target. So you can create a stub the normal way in Cloud with these settings.
