Important LikedIn option needed

I have to manage hundreds of LinkedIn accounts. This is very easy with your software. However, I need an option that can change the game for advertising on LinkedIn.

I need an option that will add a specific member to all of my conversations. This way, I do not have to login to each and every account I manage in order to see messages. If the software would add a specific user, I would be able to log into a single account and see all messages to every one of my LinkedIn accounts I manage.
