Can I amend my Complaint for the 2nd part of my case. Which is for a Civil Law Violation.

When I filed my first Complaint for Assessment of Damages-Other for Items that was stolen and the Other was for Tort violation they never answered it. So it went to a Default Judgment. Now the 2nd part. The Judge was suppose to only do Assessment of Damages but while waiting for her desicion, the Judge was given the 2nd part. I amended my complaint because of new defendants and better wording of Charges and new evidence. In my Amended Complaint I mention nothing about Assessment of Damages, which was the first part of the case. As in Law the word Damages covers a wide range of Law.But my Motion to Amend was Denied due to what there Attorney is try to say that im trying to turn the case purely Technical. Saying that I am asking for Assessment for damages again and that was already paid. In the process of filing for a Reconsideration. How can I convince the Judge that they are just trying to avoid due process.
