Remembering the previous question/intent

If the things that the user asks more about are limited, stories should be enough. Let’s pretend that you have the following intent:

## intent:know_more
- I would like to know more about that
- ...
...

And for each subject, you have a different story with a different utter after the intent above. For example, for credit card and bank account.

## story credit card
* credit_card
  - utter_credit_card
* know_more
  - utter_know_more_credit_card


## story bank account
* bank_account
  - utter_bank_account
* know_more
  - utter_know_more_bank_account
