DLP Combo rule

We are getting a request to explore the options to have a rule to look combo information in a traffic like if we can see Name & Date of birth of a client in an email.

Can it be done with the EDM? DOB can be written multiple ways so how to suppress the false positive?

If we have Multiple names\DOBs in an email. How to look for same Name with same DOBs? That may account for more False positive.

Does anyone has come across any such requirement?
