I am trying to use CP as a support panel for clients but clients from same organisations/companies(generated by leads webform) can see each other and I am looking for a solution for situation.

Thanks for help again and again...

Any directions on this subject?

I'm currently out, visiting our team in Albania. Give me some time to have a look.
Off the top of my head I'd say it won't be possbible as the customer portal uses related Account to decide what to show, but let me make sure.
