single email1 field in custom module in suiteCRM

I have a module of person type and i dont want to make all the custom views and using the default view.

As i am using email address field it is making a multiple email addresses field. How can i use a single email1 field so that no multiple email address should linked with that bean/id.

I also tried to add custom code but that is not a good approach i think. Also i want to make this field require. Why i am using this field not custom email field is i will use this email for workflows later.
Any kind of help would be much appreciated.
