ADOBE AERO: Group triggers/actions

Hi all! I have been trying to figure out if it is possible to add one trigger to a group/folder of assets. I have a proximity fence set up because I don't want people to go beyond a certain area in my scene.  The fence is modular and made up of multiple peices which I have all grouped into one folder. I want the entire fence to show at the same time when the camera enters the proximity trigger. The obvious solution that I have already attempted is to just simply set the subject of the prox trigger to the folder, but it isnt working.  If setting the trigger for the entire group  isnt possible is there at least a way to copy/paste the trigger settings so I don't have to manually set the same trigger 20x? I'm also note sure if setting the triggers on each individual asset will make them all show at once either. 
Thanks!
