It would be super great that when for example reviewing latest triggers or configuring items/triggers, there was a menu (an option) which would allow to include trigger in action. A drop down menu of sorts -> add to action -> and then you would pick an action from a list of actions and select a function (trigger==[trigger that you want to monitor] or trigger<>[trigger you want to monitor]). Or you could create a new action for selected trigger (or multiple triggers at once) on the spot, which would result in a screen similar to defining a new action as it is now, except that under 'conditions', there would be selected triggers already, next to the already existing ones (trigger==problem and 'not in maintenance')

This would truly rock.
