I love the feature that lets you add a tag to a contact automatically when they click a link in a campaign, but it would be super useful to be able to do this en-masse for previous campaigns sent before automated tagging was setup.

I just started tagging contacts who clicked a specific kind of link in my latest email, but I've sent several similar emails in the past, and I'd like to go back and tag all the contacts who clicked similar links in previous emails.

Currently, the only "mass update" I can do is to change the value of a custom field for all those contacts, but there's no option to apply a tag to all of them.
