Having a finer control on dialogue management in RASA

I am making a voicebot with ASR as front end. I want to have a more finer control on the flow of conversation in rasa bot. Rules and stories are helping to some extent, but my requirement is, for eg -

If customer is silent ( a ’ silence’ keyword is passed as input in such cases ) in first question / second question, then the bot should directly go to third question

Basically, i want to control bot response in exceptional situations by the use of response serial number. Is there any way to achieve it in rasa ?

a ’ silence’ keyword is passed as input in such cases

The front end can tigger an intent when the ‘slience’ keyword is received. This doc shows the API call to trigger an intent:
