Workspace Sharing

Currently the option to share Document Types and Tags are available. In my opinion a workspace is more like a separate department or division. Can you please create an ability to Share Contacts and Companies as well. The Workpace is set up moreso like a segregated division and less like a Team capability where clients/companies might need access to certain things but not all without having to re-create the data again which could lead to more user errors and duplicating details.
