Attributes not published and not sent to outbounds

Current situation: Rockwool is preparing the data for third party and some attributes should not be sent out and published to the third party. They are confidential. In Inriver there is no possibility to prevent some attributes from being sent to outbound systems and third parties. Currently we send data in excel format through export functionality.

Target: Users have possibility to mark in PIM attributes which shouldn't be sent out to third party.

Users would like to visualize in UI that attribute is blocked from being sent out.
