Multiple Fields in One Look up Field

Multiple Fields in One Look up Field

In form A we have a field for Contact Name and Contact Email.  Also in form A (in case the customer has more than one contact person) we have fields for Contact2, Email2, Contact3, and Email3.  In form B, we have a look up field that pulls from the Contact Name field only and than auto populates that persons email in from B.

Is it possible that the look up field in form B could also pull the data into it from Contact2 or Contact3 if data is present there and also populate the email field?
Cheers!
