Add a test to a Multi-Test (NTC) that’s already running

One of the features long-time BlazeMeter power users love is the ability to add additional load or entirely new test logic to a large test that’s already running. No need to stop, reconfigure and re-launch: Just launch an additional test and join it to the Multi-Test in progress.  This feature is now live in New Test Create (NTC), also known as BlazeMeter “V4”.
