How to associate "Test Iterations" in Visual studio to test iterations in Azure test plans

I'm running a test automation repository with test written in SpecFlow running nUnit on Visual Studio. Some of the test scenarios running a table of test parameters generating many test cases per test scenario. In Visual Studio the test cases are listed in "Test Explorer" and each test case carry a title that include all test parameters for each iteration, which makes is very long title. For example: "Security_ScreensFeature._01_NotLoggedIn_NoAccessWhenUsingShowScreenActionConnectedToObjectForScreenWithSecurity("Security_Alias_Modal_Popup_with_security_1","btnShowModalAliasPopupWithSecurity_Admin",null)"

Problem 1:

When trying to associate test cases in visual studio to test cases in Azure Test Plans, sometimes the title is too long to handle, and Azure refuses the association since the title is longer than 256 characters. I can't shorten the title by shortening the test input parameters since the same parameter is used in the product I'm testing, and changing it will break the test environment. Is there any solution to this problem?

Problem 2:

In Azure Test Plans I can create test Iterations by using "test parameters" but it is not possible to associate these test iterations to the test iterations in Visual Studios Test Explorer. In VS each iteration is a "test case" and can be associated to a "Test Case" in Azure, not to a test iteration. That means I cannot use test parameters and need to create a separate test case for each iteration in Azure to be able to associate it to the test cases (iterations) in Visual Studio. Having test scenarios with 30 iterations each will make my work in Azure Test Plans 30 times bigger. Is there a way around this problem?
