Range of Debugging IP Addresses

I was wondering if there was a way to add a range of IPs to the "Debugging IP Addresses" page in the CF Administrator.  I would like to use this feature to keep most unwanted people from seeing the messages, but everyone who needs access is using dynamic IP addresses or is using a VPN so I can't have a set list of a few IPs.  For example, could I add something like 123.123.*.*   ? 

Thanks,

Matt
