Context and RASA NLU

I’m using chat framework wherein I’m storing the context of the conversation at each step. But I’m not sure how to change the intent classification in Rasa NLU based on the context I’m storing. Also, I cannot use Rasa core or Rasa X because that would mean recreating the bot again. Could someone give me a clue on this?

currently, Rasa NLU is context independent, context is managed by rasa core
