Thanks for your message. Exported test run results are currently only provided in case you want to further process this data (for example, to build your own custom report with Excel). There is currently no way to use this data with TestRail itself.
Could you explain in which kind of situations you would want to copy test results? This would help us better understand your feature request. Please note that you can already copy test cases in TestRail, but not yet results. Thanks!
there can be 2 different platoforms (Linux, Win) with similar test plans and test results. But the several steps are usually different.
Or tests with real and fake objects have a same test plan but different test results.
