problem with multiple distinct endpoints in a Test Suite

I am trying to record a test suite in soapUI with three Test Cases. I want each of the test cases to go against a different IP address (because there are multiple servers in the farm.) the problem that I am running into is that when I change the endpoint for one of the test cases, it is changing the endpoint for the other test cases. I need for each test case to have a distinct endpoint (ie IP address).
