This much is true.
However, be aware that any schedule change, equipment substitution, or even system sweep triggered by who knows what will bump your wife back into E-.
And now to answer your initial question, no. Unfortunately, UA does not have the ability to "link" your records. The best that agents can do is annotate both records; but since these are just comments, they won't be recognized by the system in the events I noted above.
This has been discussed before (though not recently), so you're OK
