Add Option to Select All Assets for a Threat Rule

When creating a Threat Rule, Internal Contacts, Locations, and Suppliers to which you want the rule to apply have to be added manually and 1 by 1 to the rule. I know that one of my clients is going to want to create a Threat Rule that can be applied to all Locations that are being monitored by Threat Intelligence - in there case, they plan to monitor 1400 Locations and adding each of them to a Threat Rule one at a time will be incredibly cumbersome. My suggestion is that we add an option whereby the user can easily select all Internal Contacts, Locations, or Suppliers that are being monitored by Threat Intelligence or can add using a Tag when creating a Threat Rule.
