Thanks for your post! Currently the add_run methods wouldn’t support filtering test cases, and you would need to specify any IDs as needed within the case_ids field of the request. In order to do this, you would need to handle this programmatically, e.g. by using the get_cases method to retrieve the list of test cases and parsing the fields/cases that you need to build your test case ID array that could then be used to populate the case_ids field of the add_run request. Hope this helps!
