Randoop generates tests with same name for all of the classes

I want to generate tests for 200 classes (I have put their classes names in --classlist txt) but Randoop generates RegressionTest0.java to RegressionTestN.java and replaces generated files because they have same name. Is it possible for Randoop to generate tests files with same name as class names, I have put in the classlist file? For example, I have a KMeans.java class and Randoop generate KMeans0.java to KMeansN.java instead of RegressionTest.java? Thanks.
