Customizing work items - new attributes onto old work items
I created about 300 work items (user stories), then added a new custom attribute to the user story work item type. The new attribute appears on new work items I create, but doesn't on the existing work item instances.
How can I get it to appear, so I can make use of the attribute in all the 300 existing work items?
