-- In LRC, there is no option to create a scenario based on ' group completion'.
As an alternative, you might ask to provide a time delay to start the next group / script. however, if the response time increases, than the provided pacing, then the next group might start run early. It's required, for the case, where we are fetching data through the first script and trying to run the next script based on the out put of previous script. Please go through the attached screenshot for reference
If these same options can be made available then it will help in creating an incremental scenario.
