Not sure if this is possible already or not. I haven't been able to find the ability to do so.
It would great if you could exclude certain "Popular Services" from the portal view that the end-users see. Often times I will be doing on-boarding for a new hire and one of the popular services is "Terminate Employee". It would be great to exclude it from that particular list.
In the same vain, it would also be great to allow certain users have certain services available/viewable and the majority of employees do not have the capability.
