Hi Elvio,

As Ben mentions, there is quite a lot to take into account when considering to mask a service.

That said, I believe the services you are referring to are quite static and include full elements, with each one only belonging to a single service. This greatly reduces the risk to introduce any unwanted behaviour while performing a mask.

A simple script which iterates through the service and (un)masks each element is probably the best solution here. This script could then be triggered on schedule or through a Visual Overview button click.
