We have quite a few custom properties that get added, though quite a few of them could be automatically detected.
For example we have the following custom property
Region
-London
-New York
-Dubai
etc
All of which need to be manually selected, though this could be worked out using the same "Dynamic Query" that the groups uses and allocated automatically.
Region Default Value: London
Rule 1: IF hostname includes LON THEN Value: London
Rule 2: IF IP Address is part of 10.0.0.0/24 subnet THEN Value: Dubai
etc
This would greatly help enhance the Node Discovery Auto Import feature!
