Reports in 1P for which data (email, address, etc.) is assigned to which 1P record?

Thanks, Dave. I've been using the Search function so far to do it but that approach has 2 weaknesses as I see it:

a) accuracy. It's based on a text search rather than a specific data field assignment e.g. if I write a note that the old email address was X then it'll show false positives in the text search
b) workflow. The MFA report in watchtower is a good workflow tool as it highlights specifically which Logins should be converted to MFA

Ideally, I'd like to see a report for each field name that I can enter in a 1P record ie a report for 'Email' that shows which value for that email field is assigned against which 1P record. This would help act as a workflow if I want to migrate email addresses for example.
