Efficient method for editing application Firewall rules?


I have a bunch of rules added to the list of application Firewall rules, so there are list which has become quite long. My wish now is to arrange all the individual ip addresses into ranges.

The problem with using the Comodo Firewall rules interface is that it takes a long time finding the ip addresses belonging to the somewhat same ranges and then a long time sorting them into ascending or descending order.

Is there a more efficient way of editing the application rules list? Like for example editing the rules list with a text editor or if in the Registry exporting the rules into a *.reg file and the edit it with a text editor from there?
