Be able to filter for contacts that have an email address but no name

I have a lot of email addresses that get automatically added to my contacts from things like email threads or calendar invites. A significant number of times these emails are for people who are already in my contact list, I just don’t have their email address associated with their profile. It would be great if the system was a bit smarter about seeing, for example, first name.last name@ or a first initial.lastnam@ email address and suggesting if it’s possibly a match for one of the closest matching contact names.

It’s challenging to having to manually try to identify every time I can find an instance of one of these emails and then go find the existing contact to merge to instead. (there seems to be no easy way to do a search for contacts that I only have an email address for and no other data points… Even trying to ask the AI copilot to list them all for me seems to fail)
