In order to better accomodate those working and monitoring a cloud environment (most specifically AWS), it would be nice to be able to set Discovery Rule without using an IP range. This would be very useful for those that run in an entirely "auto-registration" environment.

This problem arises from aggregate information being collected on groups. I want to arbitrarily decide when to remove hosts from groups so their data no longer collects in aggregates. Right now the Discovery action that changes groups requires information that's defined from a Discovery Rule that requires an IP range, which is unavailable.
