Groups of NASs by IP

Hi, I would like to group NASs by ip address but as I have a few hundred, I don't want to maintain a list. Can I configure ip address ranges in huntgroups eg. Group1 NAS-IP-Address == 192.168.1.101 - 105 If not, can I use regular expressions? How else can I do this? What is the best way?
