Tenable ONE ASM

Anyone have experience with this module? I'm trying to setup subscriptions to match what we have in [Shodan.io](http://Shodan.io) but for some reason the simple logic of "alert me when something new is seen" escapes the logic of Tenable ONE UI... Or am I missing the point, I want to know when something new in a /24 block spins up..... Why does Tenable ONE want it to be pre-tagged or pre-determined in a query.... is there another way?
