There is now a textarea named <Single test command> with description "This command when present will be executed before the plug-in iterates the retrieved automated test cases. It is useful when you have a set of automated test cases and a single test command that executes a test suite, for instance."

My request for another new feature would be another textarea for another POST <Single test command>, that will be (optionally) executed after the iteration of the test cases.

That way i could use the first <Single test command> to start setting up my testNG xml file, and during the iteration process I could add the requested Test Cases to the testNG xml file and I could use this new POST <Single test command>-field to finally execute my whole testNG suite of Test Cases.

I don't see how I can do that only from the one and only now existing <Single test command>, because I don't have all the info available yet at that point in the plug-in process of actions

This new requested another POST <Single test command>-field MUST be executed before the plug-in's process of collecting the results from the reports.
