[otrs] Can customer users view each others tickets?

Is it possible to configure OTRS in a way so it is possible for all customer users belonging to the same "company" to view each others tickets and aswers? In my help desk we are supporting users from 12 different companies and we would very much like to allow users from the same companies to view each others tickets. Is it possible to configure OTRS to support this feature? I am very interested in hearing suggestions on how to realize that. Thanks Stig Rasmussen
