If all your vendors are defined as customer profiles, the view of All Customer Vendors would display what you are needing. If its a mix of customers, companies and support reps, you'd have to switch between views.
We are looking at ways to allow our customers to build their own views. Rather than try and anticipate everyones needs, if we provide some of the basic views and a way to easily generate your own views, this would address what you need. Until then, hopefully looking at the vendor view of customers will work.
We appreciate hearing about your needs as it allows us to enhance the application.
