Add new header to HttpProtocolBuilder later in simulation.

I need all requests in my scenario have specific header except very first request.
But since HttpProtocolBuilder apply to whole scenario, I have that header for the first one too.

Is there a possibility to update HttpProtocolBuilder on the fly during the simulation with new header or disable HttpProtocolBuilder properties for particular request in simulation?

Maybe try overriding this header with a fake value.

This is an interesting feature and it will be implemented in 3.4.0:
