Example of how to replace an attribute value in payload

[neocdtv]

Hi,
this is not exactly an issue, but more a question.
The recorded traffic to/from an external system uses in the body of every request payload a dynamic id in a property named "requestId" for tracing purposes. How should a configuration looks like, to match such requests properly? Currently I end up with 404 since the payload is every time different, because of this one dynamic property value.
