Access value from REQUEST payload

Is your feature request related to a problem? Please describe.

In requests and URLs it is possible to access / reference values from RESPONSE payloads but is not possible to use a value from a REQUEST payload.



Describe the solution you'd like
As we can reference RESPONSE payload values, add a REQUEST payload value reference.

Describe alternatives you've considered
This case doesn't seem to be supported right now, tried some plugins, no plugin can access a specific value from a specific JSON path from the REQUEST payload of another request.

Additional context

A use case I have:

1. Request A has a JSON in the payload, which one field is a randomly generated value (e.g. using the UUID generator)
2. Then on a Request B payload, the randomly generated value from the Request A JSON payload y required, because executes an action over an element identified with that value.
