Customer Portal Query - Company Access

Hi,

We have configured a customer to have access to 2 services. This customer is also setup with Company Access.

When the customer is in the customer portal, if they select 'All Services' and look at the user drop down, they can see every customer associated with the company, regardless of the services they have access to.

I would only like to show the customers who have access to the same services as the logged in customer.  Is this possible? 

Thanks

Greg
