Adding lots of similar hosts to a network map, creating links and binding triggers to links is a quite boring task.
It would be very convenient to perform these tasks with the power of mass update.

For example, a user goes to Configuration -> Hosts, selects hosts, that should be added to a network map.
Then in Mass update, among all the options, a user will see a new option: "Add to a network map..."
After specifying a map, another new option becomes available: "Create a link with...", so that a user could
choose a map element to link with the selected elements.
Than, if a user selected a map element to create links with, another new option becomes available:
"Add triggers to links", that shows a list of templated triggers, that exist for all of the selected hosts. If the
selected hosts have no common triggers, the list of triggers would be empty.
