Customizing new person registration form

Hello! We need to add a field to new person registration form to fill it up upon new user registration. The field is Employee ID, that can be found on Work/Home tab of Person document. What I mean, is that on Register Person - New entry form there are fields like Basic, Mail, Address, ID info, Groups, Roaming and Other. Is it possible to customize tab Other to add there one more field - Employee ID ? Perhaps, use of Lotus Designer could help? Anyone did this?

Thanks!
