If not everyone has a work email and only personal. Being able to have that hidden on the directory.

We currently have our teams hidden on the Directory. As not everyone has a work email. We would like an option to hide their personal email. As the work email field is mandatory, which is why we enter their personal one if they dont have a work one. 

We would really like all users to have the directory - teams function as we would like everyone to see each others bios. but for GDPR reasons, we cannot expose peoples personal emails.
