ROS 2 launch action when node created

The ROS 2 launch system has event handlers, e.g., OnStateTransition to trigger a launch action when a lifecycle nodes does a state transition. Is there a similar event handler (or other mechanism) to trigger a launch action, when a node is _constructed_ (so no state transition, yet)? Maybe an event handler based on the ros graph?
