SIL specification: when adding a subcomponent, no safety spec is created automatically.
When I havve component A with subcomponent B and I add a safety requirement with scope A, a safety spec for the subcomponent is created automatically.
When I first add the safety requirement and then the subcomponent, the safety spec is not created automatically.
