How to initiate concurrent Circuit Optimizations via scripting

In AEDT desktop GUI it is not possible to run concurrent Circuit Optimizations if the optimization setups are in the same circuit 'design'. It is however possible to run concurrent optimization setups if they are from different designs even if both designs are within the same project.
I am not able to achieve the same results via scripting even when setting the 'isBlocking' parameter of Optimetrics Module SolveSetup to False. The second optimization always gets put in a queue and only starts running after the first one is done.
How can this be achieved via scripting? Note that if one simply records an (IronPython) script of starting these concurrent simulations, when the script is run back, it does not achieve concurrency (even if isBlocking is changed to False).
