If the subprocess is failed, the whole test is stopped and never invoke the assertions/filters at the Execute Subprocess step in the main test case.
I want to decide whether the sub-process fails by using the assertion which set at the 'Execute Subprocess Step(s)' in the main test case.
For example, what about to change as follows?
・If the sub-process fails, a transition to a new step of the "sub-process failure step" instead of the usual "failure step".
・It returns a status of "sub-process failed to run" to the main test case.
