Is it possible to hide email aliases in the GAL? The only option I can find is to hide the main account.

One example of why this would be useful:

Our email addresses are created using first initial and last name (not the best policy, but it's ours).
User gets married, so last name changes.
User gets new email address with old address aliased to the account so they do not miss any mail during the name change.
It does not encourage everyone to use the new address when they continue to see the old address in the GAL.
