Custom Fields for Subscriptions in Customer Portal

Custom Fields for Subscriptions in Customer Portal

We need to be able to display a custom field for a subscription in the customer portal.   If the custom field is a URL we need to be able to allow the customer to click the URL from the portal.   Ideally, we can have a text string that is what is clicked but the underyling URL is loaded.

This is important to be able to allow the portal to provide access to view/edit information within our site that is not part of the subscription itself. 

I think customer custom fields are viewable in the portal but the URL is not clickable.
