Currently, users must find and use a custom rule to sort within NETs (see https://help.qresearchsoftware.com/hc/en-us/articles/4412677354383-How-to-Sort-Table-Categories-Within-Each-NET ). It would be easier to allow users to sort within a table containing both NETs and Subnets with a built-in rule rather than having them search for the custom one and apply it.
