Auto generated values in the example requests

[lazartsarev]

Hey, we have an endpoint which requires different value to be provided for each request for specific field. Is it possible to enable this functionality in our Stoplight Elements Demo by for example generating random guid for each request? How can this be integrated with the OpenAPI?
Also is it possible to transfer over automatically fields between the endpoints? For example endpoint for creating address, which returns id and when we navigate to the endpoint for looking up address the id is automatically populated there.
