Portfolio Entry Settings

Hi,
I am very confused about the Portfolio Entry Settings – that needs to be inserted. This causes some problems for my site and how the URL are shoen in Google search results – also the Breadcrumb. Is it not possible to NOT use this?

My structure: I have 3 different main product categorties. (they are in Danish, so I’ll write them in English below)

Display Systems
Office
Creative Solutions

Under each category I have place all my products as portfolio items.
So if I go to a product page (portfolio page) I put in a custom permalink. E.g. /display-systems/vip-table-display

“Display systems” is my category and “vip table display” is my product name. BUT in Google search results and i Breadcrumb it uses the “portfolio tem base” from the global settings as URL. I have typed in “products” in the “portfolio items base”. So in Google it will show this:
/products/vip-table-display. This is bad as I want the category to be included. “Display sytems” I can’t just use “Display systems” as portfolio items base, because it will then also show in my other categories. (Creative solutions) Which is not the case.

I really hope that you can follow me on this one as it is very bad for my URL and how Google is showing it. Is it possible to have support over phone if I pay for your support??
I assume that this is much easier to explain by phone. Again, this is very frustrating, so I really want to have this “issue” cleared out.
