I have a contact at Head Office (the top tier account), that needs to be able to see the service lines of the Agreements (ie Agreement Booking Setup/Product) for all of the child accounts under the Head Office. I don't think this can be done via regular portal security and I don't want to put that contact on every agreement, so my question is what is the best way to implement to maintain a secure environment but still allow this user access to the necessary agreements for all of their offices?
