How do I register several emails in a customer's file?

When we register a client, the system offers us an email field which is normally associated to the company, if we have the need to send documents to different people associated to that company we have these options available to register it:

1. 1. 2. From the customer's own tab, click Edit and in the Contact persons tab, click New and you can enter the name and email of the customer as well as the data you need.
      3. The other option is to register the data from Customers > Contact persons, click New and you can indicate Name, customer and email, as well as other available fields.
