Would like to be able to re-link a TFS item to an Aha Feature Merged

If the link between an Aha Feature and a TFS item is lost there is no way to reinstate that link.  Would really like that ability added.  Additionally, it would be great to be able to create this link from an existing item in TFS to an existing Feature in Aha, but reinstating the link for previously linked items would be a high priority.
