Currently, internal and external are using separate PW Projects for DM. We have to add external parties through "add external organization feature" and that basically creates a separate PW project for the external parties.

As of today, If we put both internal and external in a single PW Project, it will have confidentiality issue as the mail packages are available for all project members automatically as long as it's not confidential. We don't want that too.

To reach this objective, we may need an option to classify project users based on their organization in DM under the same PW Project, we could segregate users to their respective organization. Since there is organization specific classification, further permissions structure can be developed to manage organization specific permissions within the same PW Project. This also provide minor improvement on the serial number as the classification can allow unique organization prefix to be applied on the mail packages.
