This would be a great feature - many of our donors are couples and because we can’t connect contact records with other contact records (e.g. to show their relationships) we need to keep them together (especially important for when we send event invites), but then we run into the issue of not being able to send an email to their secondary address so only one partner recieves the invite. It looks like this is a feature many others would find useful too so hoping a solution is found soon
