A custom field with 2 field inside and a button for add 2 field in every click

[falinsin]

Is there a way to create a field composed internally of 2 or 3 textbox and an add button?
Pressing that button would always add 3 more fields.

I need to create a form that allows you to add contact persons.
Each contact with 2 or 3 textbox for data like name, phone, etc... so the user can press the add contact button and add 3 more fields for another contact.

I do not know if it is possible to create that type of field for example by creating a template for those three fields and an add button.
It is very important for my development that already uses angular-formly
