Can I whitelist a whole subnet on ASM 12.1?

I have several subnets that I want to whitelist (never block IP setting) for my ASM policies. When I am in the IP Exceptions page I only see the option of added a single IP at a time. Is there any way to add an IP range or subnet to my ASM policy? Thanks!

    You can add the network IP Address (e.g. 11.22.33.0) along with its netmask in decimal format (e.g. 255.255.255.0) in the optional field "Netmask". You have to repeat this for each subnet.
