Idea: A 'merge users' feature

We often have situations where a customer will contact us from multiple email addresses, which results in them having multiple user profiles in our system. This can be a real pain to deal with, as it means that we don't have a single, unified view of the customer. It would be amazing if there was a 'merge users' feature that would allow us to merge multiple user profiles into a single profile. This would be a huge time-saver for our agents, and it would also help us to provide more personalized and effective support. I know that this is a complex feature to implement, but I think it would be a huge win for many of us.
