Child Task Updates Visible from Summary Task Updates

I am wondering if we could have updates from child tasks be visible on the summary task's Updates tab, similar to how all of the updates on project tasks are visible in the project-level Updates tab. We set up all of our projects to include a summary task for each deliverable, but currently updates on child tasks can not be viewed from the summary task's Updates tab. It would be great if the Updates tab for each deliverable (summary task) could contain updates from all tasks that fold up under it.
