Amend a Special Civils Part Money Judgement case

[Anjali L.]

I just received a court date for a money judgement complaint for non payment of rent. i had filed in October when my tenant was behind by two months. By the court date she will be behind by over 6 months. Can I amend the case to add the new amount? What is the process for doing that considering the delay in getting the court date added $$$ to the balance?
