Multiple Dynamics 365 Portals on same CRM Instance

Hi, 

I'm looking to have both a Customer Portal and Partner Portal using the same Dynamics 365 CRM instance.

Is this possible, as the portal application overview states.

"Portal is an Add-On subscription for CRM Online that allows you to extend the engagement with Customer and Employee audiences into an Azure-hosted web portal. This Add-On requires a pre-existing CRM Online subscription and may only be associated with one instance per Portal. Each portal includes 1,000,000 page views per month."

Thanks

Martin
