Storyline 360: List of which triggers can be applied in multiples?

The new Trigger Wizard in Storyline 360 seems to allow you to set multiple objects at once within a single trigger. In the attached screenshot, for example, I can set something to happen based on the states of multiple objects - this is great! What a time saver.  

Which ones are like this though? I only see the option to set multiples at once during certain trigger combinations. Is there a chart somewhere? What I'd actually like to do is Action several state changes with one trigger, but this doesn't seem possible so maybe I could devise a work around if I knew which of these were able to elicit this multiple selection menu.
