Reference to test cases in test suites

It would be great if one could have a reference or link to a test case in a test suite, rather than a 'physical copy'.

I have several test suites that have the same test case in them (smoke test and regression test, for example) and currently have to make an update in two places whenever I need to update that test case. I'd love to be able to refer to a test case in another test suite, rather than have duplicate tests.
