Splunk app for Unix and Linux: Can I add more levels other than categories and group?

[jiaqya]

As of now I can see we can do categories and groups, what if we need to add more (up to 4). Is there a way or option to do this?

Not that I know of with the UI, but you probably could use that lookup, add a new column as you'd like, and use an automatic field processed to provide the new column's attribute to the hosts you desire.
