We have similar need as well, I filed a feature request for this. Add ability to specify test case Id and other query criteria to a dynamic test suite via command line. In my feature you still need to make a Dynamic Test Suite, but if they added what I requested you could specify tests to run in addition to test ids through command line (though still using Dynamic Test Suite to do it).
These features are implemented in most open source frameworks, so I’m hoping they make it simpler for us rather than harder…
