It would be nice that IP Address Groups can be defined using wildcards.
Let's say we have different subnets for branch offices and want to define an IP group for a specific node address in every branch, with current options we need to enter IP adresses one by one, but with wildcard support we can define these addresses with a single entry.
192.168.0.100
192.168.1.100
192.168.2.100
192.168.3.100
.
192.168.255.100
=192.168.0.100 0.0.255.0 (wildcard notation)
