Filling parameter values through fulfilment

[poush]

According, to the sample provided in this repository. It allows you to check the value of the parameter through agent.parameters in the slot filling process. But there is no any example of the scenario where we would like to provide those values through fulfillment.

Say, for instance, I have three required slots and based on the conversation/situation, I might want to set one or more slots value on the backend. I'm not able to see the possible way for this. A working example is in Alexa Skills, where Dialog model allows you to update slots value in the backend.
