Associate multiple automated tests in Visual Studio to a single test case in VSTS(Azure DevOps)

I am trying to associate multiple Visual Studio tests to a single test case in Azure DevOps(ADO). Currently you are able to do vice versa only - associate one Visual Studio test with multiple ADO test cases.

We are using parameters in test cases in ADO and we are using parameters in our automation framework. The difference is that parameters don't generate new tests in ADO, just a new iteration of same test case id.

While the automation framework generates a new test for each new iteration(and we like that). So in order to map our automated tests to test cases in ADO, we need to be able to map multiple Visual Studio tests to a single test case in ADO.

In the 1st screenshot I am selecting multiple test in Visual Studio and trying to associate them , but the option is disabled, when I select multiple.

In the next screenshot, I am trying to associate a Visual Studio test with a ADO test case that already has association and get an error.
