We would like the ability to add nodes to NPM even if they are offline. The reason we would like to do so is that we are contractually bound to monitor client devices from the instant they go live. With the current feature set we cannot do so and must add all the devices manually or by discovery (which is inherently flawed by it's nature) which can take considerable time.
Ideally we would like to add a device that is not online and set it to be unmanaged until the date and time it is due to go live at which point it would become managed without any further action on our part.
