Is it possible to autoclose all child attributes when closing a parent in RTC?

Typically people want it the other way around - you can only close the parent once all the children are closed.
There is a precondition for work items that does exactly this check.
You could also create a query that showed all open children for a parent, and then you could use a bulk action to close them - this would then let you review what's still open before closing, which in my mind would be the best way to close them out.
