CRM - Is it possible to allow a customer to edit all contacts under their account via a portal

Hi,

I am a new Zoho CRM user, checking out its potential.

I have created accounts that have multiple contacts associated with them. I want to allow one person to be able to update the details for *every* contact under their account.

Is this possible?
